high Nessus Plugin ID 215014

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 16.1.5 / 17.1.2 / Hotfix- BIGIP-15.1.10.6.0.11.6-ENG.iso. It is, therefore, affected by a vulnerability as referenced in the K000138932 advisory.

When the Session Initiation Protocol (SIP) application layer gateway (ALG) profile with Passthru Mode enabled and the SIP router ALG profile are configured on a Message Routing type virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.(CVE-2025-20045)

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.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K000138932.
