Appliance mode iControl REST vulnerability
F5 · BIG-IP
The flaw is an Appliance mode restriction bypass in the iControl REST interface of F5 BIG-IP, which lets a user escape the limits that Appliance mode imposes on the system. An attacker needs network access to the iControl REST interface and must already hold valid credentials with the Administrator role; no user interaction is required, and successful exploitation allows them to cross a security boundary, which the advisory ties to an undisclosed endpoint.
In all versions of BIG-IP, when running in Appliance mode, an authenticated user assigned the Administrator role may be able to bypass Appliance mode restrictions, utilizing 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.
