Local privilege escalation via DLL search-order hijacking
Published Jan 2, 2025 · Updated Jan 2, 2025
DLL hijacking in Acronis Cyber Protect 16 before build 39169 allows local users to gain elevated privileges on Windows systems. The vulnerable component loads a DLL through an uncontrolled search path, but Acronis has not identified the executable or DLL path. Exploitation requires local low-privileged access and user interaction; successful loading executes attacker code with the component's elevated rights.
