Local privilege escalation via DLL hijacking
Published Aug 12, 2021 · Updated Aug 4, 2024
DLL hijacking in Acronis Cyber Protect 15 before build 27009 and Acronis Agent before build 26226 allows local users to gain privileges. Acronis has not published the affected executable or DLL, or the precise search-path operation that loads attacker-controlled code. Exploitation requires local access and user interaction; successful hijacking executes attacker-controlled code with elevated privileges.
