Original release date: May 18, 2022

Summary

The Cybersecurity and Infrastructure Security Agency (CISA) is releasing this Cybersecurity Advisory (CSA) to warn organizations that malicious cyber actors, likely advanced persistent threat (APT) actors, are exploiting CVE-2022-22954 and CVE-2022-22960 separately and in combination. These vulnerabilities affect certain versions of VMware Workspace ONE Access, VMware Identity Manager (vIDM), VMware vRealize Automation (vRA), VMware Cloud Foundation, and vRealize Suite Lifecycle Manager. Exploiting these vulnerabilities permits malicious actors to trigger a server-side template injection that may result in remote code execution (RCE) (CVE-2022-22954) or escalation of privileges to root (CVE-2022-22960). 

VMware released updates for both vulnerabilities on April 6, 2022, and, according to a trusted third party, malicious cyber actors were able to reverse engineer the updates to develop an exploit within 48 hours and quickly began exploiting the disclosed vulnerabilities in unpatched devices. CISA was made aware of this exploit a week later and added CVE-2022-22954 and CVE-2022-22960 to its catalog of Known Exploited Vulnerabilities on April 14 and April 15, respectively. In accordance with Binding Operational Directive (BOD) 22-01, Reducing the Significant Risk of Known Exploited Vulnerabilities, federal agencies were required to apply updates for CVE-2022-22954 and CVE-2022-22960 by May 5, and May 6, 2022, respectively

Note: based on this activity, CISA expects malicious cyber actors to quickly develop a capability to exploit newly released vulnerabilities CVE-2022-22972 and CVE-2022-22973 in the same impacted VMware products. In response, CISA has released, Emergency Directive (ED) 22-03 Mitigate VMware Vulnerabilities, which requires emergency action from Federal Civilian Executive Branch agencies to either immediately implement the updates in VMware Security Advisory VMSA-2022-0014 or remove the affected software from their network until the updates can be applied.

CISA has deployed an incident response team to a large organization where the threat actors exploited CVE-2022-22954. Additionally, CISA has received information—including indicators of compromise (IOCs)—about observed exploitation at multiple other large organizations from trusted third parties.

This CSA provides IOCs and detection signatures from CISA as well as from trusted third parties to assist administrators with detecting and responding to this activity. Due to the rapid exploitation of these vulnerabilities, CISA strongly encourages all organizations with internet-facing affected systems—that did not immediately apply updates—to assume compromise and initiate threat hunting activities using the detection methods provided in this CSA. If potential compromise is detected, administrators should apply the incident response recommendations included in this CSA.

Technical Details

CISA has deployed an incident response team to a large organization where the threat actors exploited CVE-2022-22954. Additionally, CISA has received information about observed exploitation of CVE-2022-22954 and CVE-2022-22960 by multiple threat actors at multiple other large organizations from trusted third parties.

• CVE-2022-22954 enables an actor with network access to trigger a server-side template injection that may result in RCE. This vulnerability affects the following products:[1]
  • VMware Workspace ONE Access, versions 21.08.0.1, 21.08.0.0, 20.10.0.1, 20.10.0.0
  • vIDM versions 3.3.6, 3.3.5, 3.3.4, 3.3.3
  • VMware Cloud Foundation, 4.x
  • vRealize Suite LifeCycle Manager, 8.
• CVE-2022-22960 enables a malicious actor with local access to escalate privileges to root due to improper permissions in support scripts. This vulnerability affects the following products:[2]
  • VMware Workspace ONE Access, versions 21.08.0.1, 21.08.0.0, 20.10.0.1, 20.10.0.0
  • vIDM, versions 3.3.6, 3.3.5, 3.3.4, 3.3.3
  • vRA, version 7.6 
  • VMware Cloud Foundation, 3.x, 4.x, 
  • vRealize Suite LifeCycle Manager, 8.x

According to trusted third-party reporting, threat actors may chain these vulnerabilities. At one compromised organization, on or around April 12, 2022, an unauthenticated actor with network access to the web interface leveraged CVE-2022-22954 to execute an arbitrary shell command as a VMware user. The actor then exploited CVE-2022-22960 to escalate the user’s privileges to root. With root access, the actor could wipe logs, escalate permissions, and move laterally to other systems.

Threat actors have dropped post-exploitation tools, including the Dingo J-spy webshell. During incident response activities, CISA observed, on or around April 13, 2022, threat actors leveraging CVE-2022-22954 to drop the Dingo J-spy webshell. Around the same period, a trusted third party observed threat actors leveraging CVE-2022-22954 to drop the Dingo J-spy webshell at one other organization. According to the third party, the actors may have also dropped the Dingo J-spy webshell at a third organization. Note: analysis of the first compromise and associated malware is ongoing, and CISA will update information about this case as we learn more.

Detection Methods

Signatures

Note: servers vulnerable to CVE-2022-22954 may use Hypertext Transfer Protocol Secure (HTTPS) to encrypt client/server communications. Secure Sockets Layer (SSL)/Transport Layer Security (TLS) decryption can be used as a workaround for network-based detection and threat hunting efforts.

The following CISA-created Snort signature may detect malicious network traffic related to exploitation of CVE-2022-22954:

The following third-party Snort signature may detect exploitation of VMware Workspace ONE Access server-side template injection:

The following third-party YARA rule may detect unmodified instances of the Dingo J-spy webshell on infected hosts:

Note: the Dingo J-spy webshell is an example of post-exploitation tools that actors have used. Administrators should examine their network for any sign of post-exploitation activity.

Behavioral Analysis and Indicators of Compromise

Administrators should conduct behavioral analysis on root accounts of vulnerable systems by:

• Using the indicators listed in table 1 to detect potential malicious activity.
• Reviewing systems logs and gaps in logs.
• Reviewing abnormal connections to other assets.
• Searching the command-line history.
• Auditing running processes.
• Reviewing local user accounts and groups.  
• Auditing active listening ports and connections.

Table 1: Third-party IOCs for Exploitation of CVE-2022-22954 and CVE-2022-22960

Incident Response

If administrators discover system compromise, CISA recommends they:

1. Immediately isolate affected systems. 
2. Collect and review relevant logs, data, and artifacts.
3. Consider soliciting support from a third-party incident response organization to provide subject matter expertise, ensure the actor is eradicated from the network, and avoid residual issues that could enable follow-on exploitation.
4. Report incidents to CISA via CISA’s 24/7 Operations Center (report@cisa.gov or 888-282-0870)

Mitigations

CISA recommends organizations update impacted VMware products to the latest version or remove impacted versions from organizational networks. CISA does not endorse alternative mitigation options. As noted in ED 22-03 Mitigate VMware Vulnerabilities, CISA expects malicious cyber actors to quickly develop a capability to exploit newly released vulnerabilities CVE-2022-22972 and CVE-2022-22973 in the same impacted VMware products. ED 22-03 directs all Federal Civilian Executive Branch agencies to enumerate all instances of impacted VMware products and deploy updates in VMware Security Advisory VMSA-2022-0014 or to remove the affected software from the agency network until the updates can be applied.

Summary

Actions for administrators to take today:
• Do not expose management interfaces to the internet.
• Enforce multi-factor authentication.
• Consider using CISA’s Cyber Hygiene Services.

The Cybersecurity and Infrastructure Security Agency (CISA) and the Multi-State Information Sharing & Analysis Center (MS-ISAC) are releasing this joint Cybersecurity Advisory (CSA) in response to active exploitation of CVE-2022-1388. This recently disclosed vulnerability in certain versions of F5 Networks, Inc., (F5) BIG-IP enables an unauthenticated actor to gain control of affected systems via the management port or self-IP addresses. F5 released a patch for CVE-2022-1388 on May 4, 2022, and proof of concept (POC) exploits have since been publicly released, enabling less sophisticated actors to exploit the vulnerability. Due to previous exploitation of F5 BIG-IP vulnerabilities, CISA and MS-ISAC assess unpatched F5 BIG-IP devices are an attractive target; organizations that have not applied the patch are vulnerable to actors taking control of their systems.

According to public reporting, there is active exploitation of this vulnerability, and CISA and MS-ISAC expect to see widespread exploitation of unpatched F5 BIG-IP devices (mostly with publicly exposed management ports or self IPs) in both government and private sector networks. CISA and MS-ISAC strongly urge users and administrators to remain aware of the ramifications of exploitation and use the recommendations in this CSA—including upgrading their software to fixed versions—to help secure their organization’s systems against malicious cyber operations. Additionally, CISA and MS-ISAC strongly encourage administrators to deploy the signatures included in this CSA to help determine whether their systems have been compromised. CISA and MS-ISAC especially encourage organizations who did not patch immediately or whose F5 BIG-IP device management interface has been exposed to the internet to assume compromise and hunt for malicious activity using the detection signatures in this CSA. If potential compromise is detected, organizations should apply the incident response recommendations included in this CSA.

Technical Details

CVE-2022-1388 is a critical iControl REST authentication bypass vulnerability affecting the following versions of F5 BIG-IP:[1]

• 16.1.x versions prior to 16.1.2.2 
• 15.1.x versions prior to 15.1.5.1 
• 14.1.x versions prior to 14.1.4.6 
• 13.1.x versions prior to 13.1.5 
• All 12.1.x and 11.6.x versions

An unauthenticated actor with network access to the BIG-IP system through the management port or self IP addresses could exploit the vulnerability to execute arbitrary system commands, create or delete files, or disable services. F5 released a patch for CVE-2022-1388 for all affected versions—except 12.1.x and 11.6.x versions—on May 4, 2022 (12.1.x and 11.6.x versions are end of life [EOL], and F5 has stated they will not release patches).[2]

POC exploits for this vulnerability have been publicly released, and on May 11, 2022, CISA added this vulnerability its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. Due to the POCs and ease of exploitation, CISA and MS-ISAC expect to see widespread exploitation of unpatched F5 BIG-IP devices in government and private networks. 

Dection Methods

CISA recommends administrators, especially of organizations who did not immediately patch, to:

• See the F5 Security Advisory K23605346 for indicators of compromise. 
• See the F5 guidance K11438344 if you suspect a compromise. 
• Deploy the following CISA-created Snort signature:

Additional resources to detect possible exploitation or compromise are identified below:

• Emerging Threats suricata signatures. Note: CISA and MS-ISAC have verified these signatures are successful in detection of both inbound exploitation attempts (SID: 2036546) as well as post exploitation, indicating code execution (SID: 2036547).
  • SID 2036546

• SID SID 2036547

• Palo Alto Networks Unit 42 Threat Brief: CVE-2022-1388. This brief includes indicators of compromise. Note: due to the urgency to share this information, CISA and MS-ISAC have not yet validated this content.

• Cisco Talos Intelligence Group – Comprehensive Threat Intelligence: Threat Advisory: Critical F5 BIG-IP Vulnerability. This blog includes indicators of compromise. Note: due to the urgency to share this information, CISA and MS-ISAC have not yet validated this content.

• Randori’s bash script. This script can be used to identify vulnerable instances of BIG-IP. Note: MS-ISAC has verified this bash script identifies vulnerable instances of BIG-IP. 

Incident Response 

If an organization’s IT security personnel discover system compromise, CISA and MS-ISAC recommend they:

1. Quarantine or take offline potentially affected hosts.
2. Reimage compromised hosts.
3. Provision new account credentials.
4. Limit access to the management interface to the fullest extent possible.
5. Collect and review artifacts such as running processes/services, unusual authentications, and recent network connections.
6. Report the compromise to CISA via CISA’s 24/7 Operations Center (report@cisa.gov or 888-282-0870). State, local, tribal, or territorial government entities can also report to MS-ISAC (SOC@cisecurity.org or 866-787-4722).

See the joint CSA from the cybersecurity authorities of Australia, Canada, New Zealand, the United Kingdom, and the United States on Technical Approaches to Uncovering and Remediating Malicious Activity for additional guidance on hunting or investigating a network, and for common mistakes in incident handling. CISA and MS-ISAC also encourage government network administrators to see CISA’s Federal Government Cybersecurity Incident and Vulnerability Response Playbooks. Although tailored to federal civilian branch agencies, these playbooks provide operational procedures for planning and conducting cybersecurity incident and vulnerability response activities and detail steps for both incident and vulnerability response. 

Mitigations

CISA and MS-ISAC recommend organizations:

• Upgrade F5 BIG-IP software to fixed versions; organizations using versions 12.1.x and 11.6.x should upgrade to supported versions. 
• If unable to immediately patch, implement F5’s temporary workarounds:
  • Block iControl REST access through the self IP address.
  • Block iControl REST access through the management interface.
  • Modify the BIG-IP httpd configuration. 

See F5 Security Advisory K23605346 for more information on how to implement the above workarounds. 

CISA and MS-ISAC also recommend organizations apply the following best practices to reduce risk of compromise:

• Maintain and test an incident response plan.
• Ensure your organization has a vulnerability program in place and that it prioritizes patch management and vulnerability scanning. Note: CISA’s Cyber Hygiene Services (CyHy) are free to all SLTT organizations and public and private sector critical infrastructure organizations: https://www.cisa.gov/cyber-hygiene-services.
• Properly configure and secure internet-facing network devices.
  • Do not expose management interfaces to the internet.
  • Disable unused or unnecessary network ports and protocols.
  • Disable/remove unused network services and devices.
• Adopt zero-trust principles and architecture, including:
  • Micro-segmenting networks and functions to limit or block lateral movements.
  • Enforcing multifactor authentication (MFA) for all users and VPN connections.
  • Restricting access to trusted devices and users on the networks.

• Operate services exposed on internet-accessible hosts with secure configurations.
• Keep software updated.

Cyber actors routinely exploit poor security configurations (either misconfigured or left unsecured), weak controls, and other poor cyber hygiene practices to gain initial access or as part of other tactics to compromise a victim’s system. This joint Cybersecurity Advisory identifies commonly exploited controls and practices and includes best practices to mitigate the issues. This advisory was coauthored by the cybersecurity authorities of the United States,[1],[2],[3] Canada,[4] New Zealand,[5],[6] the Netherlands,[7] and the United Kingdom.[8]

Technical Details

Malicious actors commonly use the following techniques to gain initial access to victim networks.[TA0001]

• Exploit Public-Facing Application [T1190] 
• External Remote Services [T1133]
• Phishing [T1566]
• Trusted Relationship [T1199] 
• Valid Accounts [T1078]

Malicious cyber actors often exploit the following common weak security controls, poor configurations, and poor security practices to employ the initial access techniques.

• Multifactor authentication (MFA) is not enforced. MFA, particularly for remote desktop access, can help prevent account takeovers. With Remote Desktop Protocol (RDP) as one of the most common infection vector for ransomware, MFA is a critical tool in mitigating malicious cyber activity. Do not exclude any user, particularly adminstrators, from an MFA requirement. 
• Incorrectly applied privileges or permissions and errors within access control lists. These mistakes can prevent the enforcement of access control rules and could allow unauthorized users or system processes to be granted access to objects. 
• Software is not up to date. Unpatched software may allow an attacker to exploit publicly known vulnerabilities to gain access to sensitive information, launch a denial-of-service attack, or take control of a system. This is one of the most commonly found poor security practices.
• Use of vendor-supplied default configurations or default login usernames and passwords. Many software and hardware products come “out of the box” with overly permissive factory-default configurations intended to make the products user-friendly and reduce the troubleshooting time for customer service. However, leaving these factory default configurations enabled after installation may provide avenues for an attacker to exploit. Network devices are also often pre-configured with default administrator usernames and passwords to simplify setup. These default credentials are not secure—they may be physically labeled on the device or even readily available on the internet. Leaving these credentials unchanged creates opportunities for malicious activity, including gaining unauthorized access to information and installing malicious software. Network defenders should also be aware that the same considerations apply for extra software options, which may come with preconfigured default settings.
• Remote services, such as a virtual private network (VPN), lack sufficient controls to prevent unauthorized access. During recent years, malicious threat actors have been observed targeting remote services. Network defenders can reduce the risk of remote service compromise by adding access control mechanisms, such as enforcing MFA, implementing a boundary firewall in front of a VPN, and leveraging intrusion detection system/intrusion prevention system sensors to detect anomalous network activity.  
• Strong password policies are not implemented. Malicious cyber actors can use a myriad of methods to exploit weak, leaked, or compromised passwords and gain unauthorized access to a victim system. Malicious cyber actors have used this technique in various nefarious acts and prominently in attacks targeting RDP. 
• Cloud services are unprotected. Misconfigured cloud services are common targets for cyber actors. Poor configurations can allow for sensitive data theft and even cryptojacking.
• Open ports and misconfigured services are exposed to the internet. This is one of the most common vulnerability findings. Cyber actors use scanning tools to detect open ports and often use them as an initial attack vector. Successful compromise of a service on a host could enable malicious cyber actors to gain initial access and use other tactics and procedures to compromise exposed and vulnerable entities. RDP, Server Message Block (SMB), Telnet, and NetBIOS are high-risk services. 
• Failure to detect or block phishing attempts. Cyber actors send emails with malicious macros—primarily in Microsoft Word documents or Excel files—to infect computer systems. Initial infection can occur in a variety of ways, such as when a user opens or clicks a malicious download link, PDF, or macro-enabled Microsoft Word document included in phishing emails. 
• Poor endpoint detection and response. Cyber actors use obfuscated malicious scripts and PowerShell attacks to bypass endpoint security controls and launch attacks on target devices. These techniques can be difficult to detect and protect against. 

Mitigations

Applying the following practices can help organizations strengthen their network defenses against common exploited weak security controls and practices.

Control Access

• Adopt a zero-trust security model that eliminates implicit trust in any one element, node, or service, and instead requires continuous verification of the operational picture via real-time information from multiple sources to determine access and other system responses.[9],[10] Zero-trust architecture enables granular privilege access management and can allow users to be assigned only the rights required to perform their assigned tasks.
• Limit the ability of a local administrator account to log in from a remote session (e.g., deny access to this computer from the network) and prevent access via an RDP session. Additionally, use dedicated administrative workstations for privileged user sessions to help limit exposure to all the threats associated with device or user compromise. 
• Control who has access to your data and services. Give personnel access only to the data, rights, and systems they need to perform their job. This role-based access control, also known as the principle of least priviledge, should apply to both accounts and physical access. If a malicious cyber actor gains access, access control can limit the actions malicious actors can take and can reduce the impact of misconfigurations and user errors. Network defenders should also use this role-based access control to limit the access of service, machine, and functional accounts, as well as the use of management privileges, to what is necessary. Consider the following when implementing access control models:
  • Ensure that access to data and services is specifically tailored to each user, with each employee having their own user account. 
  • Give employees access only to the resources needed to perform their tasks.
  • Change default passwords of equipment and systems upon installation or commissioning. 
  • Ensure there are processes in place for the entry, exit, and internal movement of employees. Delete unused accounts, and immediately remove access to data and systems from accounts of exiting employees who no longer require access. Deactivate service accounts, and activate them only when maintenance is performed.[11]
• Harden conditional access policies. Review and optimize VPN and access control rules to manage how users connect to the network and cloud services.
• Verify that all machines, including cloud-based virtual machine instances do not have open RDP ports. Place any system with an open RDP port behind a firewall and require users to use a VPN to access it through the firewall.[12]

Implement Credential Hardening

• Implement MFA. In particular, apply MFA on all VPN connections, external-facing services, and privileged accounts. Require phishing-resistant MFA (such as security keys or PIV cards) for critical services. Where MFA is not implemented, enforce a strong password policy alongside other attribute-based information, such as device information, time of access, user history, and geolocation data. See NSA’s Cybersecurity Information on Selecting Secure Multi-factor Authentication Solutions, the National Institute for Standards and Technology (NIST) Special Publication 800-63B – Digital Identity Guidelines: Authentication and Lifecycle Management, and CCCS’s Information Technology Security Guidance – User Authentication Guidance for Information Technology Systems for additional steps to take to enable in-depth authentication security.
• Change or disable vendor-supplied default usernames and passwords. Enforce the use of strong passwords. (See guidance from NIST.)
• Set up monitoring to detect the use of compromised credentials on your systems. Implement controls to prevent the use of compromised or weak passwords on your network. 

Establish Centralized Log Management

• Ensure that each application and system generates sufficient log information. Log files play a key role in detecting attacks and dealing with incidents. By implementing robust log collection and retention, organizations are able to have sufficient information to investigate incidents and detect threat actor behavior. Consider the following when implementing log collection and retention: 
  • Determine which log files are required. These files can pertain to system logging, network logging, application logging, and cloud logging. 
  • Set up alerts where necessary. These should include notifications of suspicious login attempts based on an analysis of log files. 
  • Ensure that your systems store log files in a usable file format, and that the recorded timestamps are accurate and set to the correct time zone. 
  • Forward logs off local systems to a centralized repository or security information and event management (SIEM) tools. Robustly protect SIEM tools with strong account and architectural safeguards.
  • Make a decision regarding the retention period of log files. If you keep log files for a long time, you can refer to them to determine facts long after incidents occur. On the other hand, log files may contain privacy-sensitive information and take up storage space. Limit access to log files and store them in a separate network segment. An incident investigation will be nearly impossible if attackers have been able to modify or delete the logfiles.[13]

Employ Antivirus Programs

• Deploy an anti-malware solution on workstations to prevent spyware, adware, and malware as part of the operating system security baseline.
• Monitor antivirus scan results on a routine basis.

Employ Detection Tools and Search for Vulnerabilities

• Implement endpoint and detection response tools. These tools allow a high degree of visibility into the security status of endpoints and can help effectively protect against malicious cyber actors.
• Employ an intrusion detection system or intrusion prevention system to protect network and on-premises devices from malicious activity. Use signatures to help detect malicious network activity associated with known threat activity.
• Conduct penetration testing to identify misconfigurations. See the Additional Resources section below for more information about CISA’s free cyber hygiene services, including remote penetration testing.
• Conduct vulnerability scanning to detect and address application vulnerabilities. 
• Use cloud service provider tools to detect overshared cloud storage and monitor for abnormal accesses.

Maintain Rigorous Configuration Management Programs

• Always operate services exposed on internet-accessible hosts with secure configurations. Never enable external access without compensating controls such as boundary firewalls and segmentation from other more secure and internal hosts like domain controllers. Continuously assess the business and mission need of internet-facing services. Follow best practices for security configurations, especially blocking macros in documents from the internet.[14]

Initiate a Software and Patch Management Program 

• Implement asset and patch management processes to keep software up to date. Identify and mitigate unsupported, end-of-life, and unpatched software and firmware by performing vulnerability scanning and patching activities. Prioritize patching known exploited vulnerabilities.
