DescriptionCVE.org

When running in Appliance mode, a directory traversal vulnerability exists in an undisclosed iControl REST endpoint that may allow an authenticated attacker with administrator role privileges to cross a security boundary and delete files. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

AnalysisAI

Directory traversal vulnerability in F5 BIG-IP iControl REST endpoint when running in Appliance mode allows authenticated administrators to delete arbitrary files, crossing security boundaries. The vulnerability requires high-privilege administrator role access and network connectivity to the iControl REST interface, but no user interaction. Patch availability confirmed from F5; no active exploitation reported.

Technical ContextAI

The vulnerability exists in an undisclosed iControl REST endpoint-the primary management interface for F5 BIG-IP appliances. It is a path traversal flaw (CWE-35) that permits directory traversal sequences in file path parameters, enabling an attacker to escape the intended file directory and access the filesystem hierarchy. This occurs specifically when BIG-IP is deployed in Appliance mode, a managed security appliance configuration. The iControl REST API is network-accessible, but exploitation requires prior authentication and administrator-level privileges, limiting the attack surface to trusted internal administrators or accounts compromised at the admin tier.

RemediationAI

Apply the vendor-released patch from F5 advisory K000160911 (https://my.f5.com/manage/s/article/K000160911). Exact patched version numbers are not specified in available data; consult the F5 advisory for supported version upgrade paths. As interim compensating controls: (1) Restrict network access to the iControl REST endpoint to trusted administrative networks using firewall rules or F5 management port restrictions-blocks remote exploitation but impacts legitimate remote administration; (2) Audit and minimize the number of accounts with administrator role privileges-reduces insider attack surface but may impact operational flexibility; (3) Enable comprehensive audit logging of all iControl REST API calls and file operations-detects exploitation post-fact but does not prevent it. Prioritize patching as the primary remediation.
