F5 Networks BIG-IP : BIG-IP AFM vulnerability (K60344652)

high Nessus Plugin ID 144361

Language:

Synopsis

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

Description

On the BIG-IP AFM, when a Protocol Inspection Profile is attached to a FastL4 virtual server with the protocol field configured to either Other or All Protocols, the TMM may experience a restart if the profile processes non-TCP traffic. (CVE-2020-27714)

Impact

The affected BIG-IP system may temporarily fail to process traffic as it recovers from a Traffic Management Microkernel (TMM) restart. If the BIG-IP system is configured for high availability (HA), it fails over to a peer system.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K60344652.
