F5 Networks BIG-IP : BIG-IP TMM Ram Cache vulnerability (K22113131)

high Nessus Plugin ID 134957

Language:

Synopsis

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

Description

The TMM process may produce a core file in some cases when Ram Cache incorrectly optimizes stored data resulting in memory errors. RAM Cache is a BIG-IP feature used to accelerate HTTP traffic and can be enabled in a Web Acceleration profile. (CVE-2020-5861)

Impact

The BIG-IP system temporarily fails to process traffic as it recovers from a Traffic Management Microkernel (TMM) restart, and devices configured in a device group may fail over.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K22113131.
