CVE-2024-34014· NVD / CVE Program· CNA Acronis

Arbitrary file overwrite during recovery due to improper symbolic link handling.

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.19% (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 Backup extension for Plesk 1.8.6.599; Acronis Acronis Backup plugin for cPanel & WHM 1.8.3.818, 1.9.1.892; Acronis Acronis Backup plugin for DirectAdmin 1.2.2.181.

Low priority for now. Upgrade to Acronis Acronis Backup extension for Plesk 1.8.6.599; Acronis Acronis Backup plugin for cPanel & WHM 1.8.3.818, 1.9.1.892; Acronis Acronis Backup plugin for DirectAdmin 1.2.2.181 or later.
