Summary
by MITRE • 05/05/2022
On all versions of 16.1.x, 15.1.x, 14.1.x, 13.1.x, 12.1.x, and 11.6.x of F5 BIG-IP (fixed in 17.0.0), a cross-site request forgery (CSRF) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility. This vulnerability allows an attacker to run a limited set of commands: ping, traceroute, and WOM diagnostics. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

The CVE-2022-1389 vulnerability represents a critical cross-site request forgery flaw within F5 BIG-IP systems across multiple supported versions including 16.1.x, 15.1.x, 14.1.x, 13.1.x, 12.1.x, and 11.6.x, with the issue resolved in version 17.0.0. This vulnerability resides in an undisclosed page within the BIG-IP Configuration utility, making it particularly dangerous as attackers cannot easily identify the specific endpoint that is compromised. The vulnerability operates under the Common Weakness Enumeration category CWE-352, which specifically addresses cross-site request forgery vulnerabilities. From an operational security perspective, this flaw allows remote attackers to execute a limited but potentially damaging set of commands including ping, traceroute, and WOM diagnostics without requiring authentication, effectively bypassing the system's access controls.
The technical implementation of this CSRF vulnerability exploits the lack of proper anti-CSRF tokens or validation mechanisms within the affected configuration utility pages. When a user visits a malicious website or clicks on a crafted link, the attacker can leverage the user's existing authenticated session to perform unauthorized operations against the BIG-IP system. The restricted command set, while seemingly limited, provides attackers with network reconnaissance capabilities that can be leveraged for further exploitation. The ping and traceroute commands enable network mapping and topology discovery, while WOM diagnostics can reveal system information and potentially expose configuration details. This vulnerability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, as it allows for command execution through the web interface. The fact that this vulnerability affects such a broad range of versions indicates a fundamental flaw in the authentication and session management mechanisms of the F5 BIG-IP platform, particularly in its configuration utility components.
The operational impact of CVE-2022-1389 extends beyond simple command execution, as it provides attackers with a foothold for more sophisticated attacks within network infrastructure. Network reconnaissance capabilities through ping and traceroute operations can help attackers map network topologies and identify potential targets for lateral movement. The WOM diagnostics functionality, while seemingly innocuous, can expose sensitive system information that could be used to tailor more targeted attacks against the BIG-IP system or adjacent network components. Organizations running affected versions face significant risk of unauthorized access to critical network infrastructure, potentially enabling attackers to establish persistent access or disrupt network services. The vulnerability's presence in versions that have reached End of Technical Support (EoTS) creates additional risk as organizations may not receive security updates or patches, leaving them exposed to exploitation. This vulnerability demonstrates the importance of maintaining current software versions and implementing network segmentation to limit the impact of such flaws, as the affected systems operate within critical network infrastructure where unauthorized access can have cascading effects on overall security posture.
Organizations should immediately implement mitigations including applying the vendor-provided patches for version 17.0.0 or upgrading to supported versions that contain the necessary security fixes. Network administrators should also consider implementing additional controls such as web application firewalls to detect and prevent CSRF attacks targeting the affected configuration utility pages. The vulnerability highlights the critical importance of regular security assessments and patch management programs, particularly for critical infrastructure components like load balancers and firewalls. Security monitoring should be enhanced to detect unusual command execution patterns and unauthorized access attempts to configuration utilities. The affected systems should be placed behind additional security controls such as network access controls and multi-factor authentication requirements to reduce the attack surface and limit the potential impact of successful exploitation attempts.
