CVE-2022-3405· NVD / CVE Program· CNA Acronis

Code execution and sensitive information disclosure due to excessive privileges assigned to Acronis Agent.

Noroxi assessment

Priority: Monitor (action score 37/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 5.3% (FIRST EPSS); higher than 92.5% of all records.
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Acronis Acronis Cyber Backup 12.5 16545; Acronis Acronis Cyber Protect 15 29486.

Low priority for now. Upgrade to Acronis Acronis Cyber Backup 12.5 16545; Acronis Acronis Cyber Protect 15 29486 or later.
