Local privilege escalation via DLL hijacking
Published Aug 5, 2021 · Updated Aug 3, 2024
DLL hijacking in Acronis True Image before 2021 Update 4 for Windows allows local users to escalate privileges. Acronis has not disclosed which executable resolves the attacker-controlled DLL or which writable search location enables the unsafe load. Exploitation is local and requires user interaction; successful hijacking executes attacker-controlled library code with elevated privileges.
