When a BIG-IP APM access policy and an OAuth profile is configured on a virtual server, specific malicious traffic can lead to Remote Code Execution (RCE).

Impact:
This vulnerability allows an unauthenticated attacker to perform remote code execution. The BIG-IP system in Appliance mode is also vulnerable. This is a data plane issue; there is no control plane exposure.




Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
