DescriptionNVD

A vulnerability exists in BIG-IP and BIG-IQ systems where a highly privileged, authenticated attacker with at least the Resource Administrator role can create SNMP configuration objects through iControl REST or the TMOS shell (tmsh) resulting in privilege escalation.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

AnalysisAI

Command injection in F5 BIG-IP and BIG-IQ SNMP configuration allows highly privileged Resource Administrators to escalate privileges to root via crafted iControl REST API calls or TMOS shell commands. Despite the high CVSS score (8.7), exploitation requires existing Resource Administrator credentials, significantly limiting real-world attack surface to insider threats or post-compromise scenarios. …
