Detection Guidance

This vulnerability can be detected by checking for unquoted service paths in the affected services, specifically RemoteBackup and RemoteBackup_webServer, on systems running Vembu StoreGrid 4.0.

A common method to detect unquoted service paths is to use the Windows command line to query the service paths and look for unquoted spaces.
