CVE-2024-45770: Pcp: pmpost symlink attack allows escalating pcp to root user

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.28% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: pcp (AlmaLinux:8) 5.3.7-22.el8_10; pcp-conf (AlmaLinux:8) 5.3.7-22.el8_10; pcp-devel (AlmaLinux:8) 5.3.7-22.el8_10.

Low priority for now. Upgrade to pcp (AlmaLinux:8) 5.3.7-22.el8_10; pcp-conf (AlmaLinux:8) 5.3.7-22.el8_10; pcp-devel (AlmaLinux:8) 5.3.7-22.el8_10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability was found in Performance Co-Pilot (PCP). This flaw can only be exploited if an attacker has access to a compromised PCP system account. The issue is related to the pmpost tool, which is used to log messages in the system. Under certain conditions, it runs with high-level privileges.
