Name of the Vulnerable Software and Affected Versions BIG-IP versions 16.1.x before 16.1.2

Description The issue occurs when the 'Respond on Error' setting is enabled on the Request Logging profile and configured on a virtual server, allowing undisclosed requests to cause the Traffic Management Microkernel (TMM) to terminate.

Recommendations For BIG-IP versions 16.1.x before 16.1.2, update to version 16.1.2 or later to resolve the issue. As a temporary workaround, consider disabling the 'Respond on Error' setting on the Request Logging profile until a patch is available. Restrict access to the virtual server configured with the Request Logging profile to minimize the risk of exploitation.
