Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 16.1.6 / 17.1.2.2 / BIGIP-15.1.10.7.0.4.5-ENG. It is, therefore, affected by a vulnerability as referenced in the K000149952 advisory.

 When a BIG-IP PEM system is licensed with URL categorization, and the URL categorization policy or an iRule with theurlcatcommand is enabled on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate.(CVE-2025-35995)

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
