Cobian Backup Gravity 11.2.0.582 – ‘CobianBackup11’ Unquoted Service Path

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.

Mitigation:

Ensure that all services have a fully qualified path to the executable.
