Local privilege escalation via DLL search hijacking
Published Jan 2, 2025 · Updated Jan 2, 2025
DLL hijacking in Acronis Cyber Protect 16 for Windows before build 39169 allows local users to escalate privileges through library loading. Acronis identifies an uncontrolled DLL search path but has not disclosed the affected executable, DLL name, or writable search location. Exploitation requires low-privileged local access and user interaction; successful loading exposes data and permits modification without reported service interruption.
