CVE-2022-45452

Local privilege escalation via insecure folder permissions

Published May 18, 2023 · Updated Jan 22, 2025

Local privilege escalation in Acronis Agent before build 30430 and Cyber Protect 15 before build 30984 lets local users gain elevated access. Acronis attributes the flaw to insecure folder permissions but does not identify the folder or unsafe access-control entries. Windows access and low privileges are required, and exploitation can compromise confidentiality, integrity, and availability.
