Local privilege escalation via DLL search hijacking
Published Apr 2, 2026 · Updated Apr 2, 2026
DLL search-order hijacking in Acronis True Image for Windows before build 42902 allows local users to gain elevated privileges. Acronis has not published the executable, directory, or DLL search operation that loads an attacker-controlled library. Exploitation requires low-privileged local access, user interaction, and complex conditions, after which attacker-controlled code runs with elevated privileges.
