CVE-2022-0483

Local privilege escalation via uncontrolled search path

Published Feb 11, 2022 · Updated Sep 17, 2024

Uncontrolled search path handling in Acronis VSS Doctor before build 53 allows local users to elevate privileges on Windows. The vendor identifies insecure folder permissions but does not disclose the affected folder, loaded file, or unsafe search operation. A low-privileged local account is required, and successful exploitation grants elevated execution without user interaction.
