CVE-2026-34176 Details
Description
When running in Appliance mode, an authenticated remote command injection vulnerability exists in an undisclosed iControl REST endpoint. A successful exploit can allow the attacker to cross a security boundary. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A remote command injection vulnerability has been identified in an undisclosed iControl REST endpoint, applicable to F5 BIG-IP systems running in Appliance mode. This vulnerability allows authenticated attackers with administrator privileges to execute arbitrary commands on the system via the BIG-IP management port or self IP addresses, bypassing Appliance mode security. The issue is confined to the control plane, with no exposure on the data plane.
Users can upgrade to BIG-IP versions 17.5.1.6, 17.1.3.2 or 21.0.0.2, depending on their current version. For BIG-IQ Centralized Management, no update is currently available. Until a fixed version is installed, access to the iControl REST interface can be restricted through self IP addresses or the management interface, limiting the attack surface.
