## Technical details

A DLL hijacking vulnerability (CWE-427: Uncontrolled Search Path Element) exists in Acronis True Image for Windows before build 42902. The application fails to properly validate or restrict the search path used to load dynamic link libraries (DLLs), allowing a local attacker with low privileges to place a malicious DLL in a directory searched by the application. If a user with higher privileges or a system process executes the application, the malicious DLL is loaded and executed with those elevated permissions. Exploitation requires local access and some level of user interaction or specific environmental conditions (high complexity). A fix is available in build 42902 and later.
