CVE-2026-32643 Details
Description
A vulnerability exists in BIG-IP and BIG-IQ systems where a highly privileged, authenticated attacker with at least the Certificate Manager role can modify configuration objects that allow running arbitrary commands. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A vulnerability exists in F5 BIG-IP and BIG-IQ systems, specifically in versions of BIG-IP 21.0.0, 17.5.0 through 17.5.1, 17.1.0 through 17.1.3, and BIG-IQ 8.4.0 through 8.4.1. This vulnerability allows a highly privileged, authenticated attacker with the Certificate Manager role to modify configuration objects that can execute arbitrary commands. On BIG-IP systems, this could bypass Appliance mode restrictions, crossing a security boundary in such deployments. The vulnerability is a control plane issue, with no exposure on the data plane.
Users can upgrade to BIG-IP versions 21.0.0.2, 17.5.1.6, or 17.1.3.2. For BIG-IQ, version 8.4.1 is recommended. If immediate upgrade is not possible, access can be restricted to the BIG-IP or BIG-IQ Configuration utility and command line through SSH, limiting the attack surface. Trusted networks or devices can be used to block access through self IP addresses or the management interface.
