NVD Description

Note: Versions mentioned in the description apply only to the upstream pcp-pmda-gpfs package and not the pcp-pmda-gpfs package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.
