Local privilege escalation via untrusted DLL search
Published Jan 31, 2025 · Updated Feb 26, 2026
DLL hijacking in Acronis Cyber Protect Cloud Agent before build 39378 allows local users to gain elevated Windows privileges. Acronis identifies an untrusted DLL search path but does not disclose the affected executable, library name, or writable search location. Exploitation requires low-privileged local access and control of a searched path; successful loading runs attacker code with the agent process's higher privileges.
