CVE-2024-55542: Local privilege escalation due to excessive permissions assigned to Tray Monitor service.

MediumCVSS 4.4 · v3.0—No exploit Fix available

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: 0.16% (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: Acronis Acronis Cyber Protect 16 39169; Acronis Acronis Cyber Protect Cloud Agent 35895.

Low priority for now. Upgrade to Acronis Acronis Cyber Protect 16 39169; Acronis Acronis Cyber Protect Cloud Agent 35895 or later.
