Vulnerability from github – Published: 2026-09-22 15:32 – Updated: 2026-09-22 21:31

Details

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.

Vulnerability from cvelistv5 – Published: 2026-09-22 14:17 – Updated: 2026-09-23 03:55

Title

BIG-IP APM OAuth vulnerability

Summary

When a BIG-IP APM access policy and an OAuth profile are configured on a virtual server, specific malicious traffic can lead to remote code execution (RCE). This vulnerability is only present when BIG-IP APM is configured as an OAuth Authorization Server. Deployments using APM strictly as an OAuth Client / Resource Server (without OAuth authorization server profiles configured) are not affected by this vulnerability. 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.
