F5 Networks BIG-IP : BIG-IP HTTP/2 vulnerability (K65372933)

high Nessus Plugin ID 136143

Language:

Synopsis

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

Description

Under certain conditions, the Traffic Management Microkernel (TMM) may generate a core file and restart while processing SSL traffic with an HTTP/2 full proxy. (CVE-2020-5875)

Impact

If you have enabled HTTP/2, Message Routing Framework (MRF), and SSL, a certain request sequence can trigger a condition that may cause TMM to generate a core file and restart. An attacker may be able to cause a BIG-IP system to produce a core file, disrupting the flow of traffic and causing a failover to a standby system.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K65372933.
