Acronis True Image OEM 19.0.5128 – ‘afcdpsrv’ Unquoted Service Path

Acronis True Image OEM 19.0.5128 suffers from an unquoted search path issue impacting the service 'afcdpsrv'. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user’s code would execute with the elevated privileges of the application.

Mitigation:

To mitigate this vulnerability, Acronis recommends users to upgrade to the latest version of the software. Additionally, users should ensure that all software on their systems is kept up to date and regularly patched to prevent potential security vulnerabilities.
