Local privilege escalation via DLL search-path hijacking
Published Mar 5, 2026 · Updated Mar 5, 2026
DLL hijacking in Acronis Cyber Protect 17 before build 41186 allows local users to elevate privileges on Windows systems. A privileged process resolves a DLL through a search path containing a location controlled by a lower-privileged user; Acronis has not named the executable, DLL, or directory. Exploitation requires existing low-privileged local access and a controllable search location, and successful execution grants elevated code execution.
