Name of the Vulnerable Software and Affected Versions F5 BIG-IP versions 12.0.0 through 12.1.2 F5 BIG-IP versions 13.0.0

Description The issue is related to the iControl REST service in F5 BIG-IP products, which improperly re-validates cookies when converting them to X-F5-Auth-Token tokens. This allows once-valid but now expired cookies to be converted to valid tokens, potentially granting unauthorized access to the iControl REST interface.

Recommendations For versions 12.0.0 through 12.1.2, update to a version outside of this range to resolve the issue. For version 13.0.0, update to a version later than 13.0.0 to resolve the issue. As a temporary workaround, consider restricting access to the iControl REST interface to minimize the risk of exploitation.
