-
Verify Synology DSM is deployedConfirm the target system is running Synology DSM. This vulnerability affects only Synology DSM with the C2 Identity Edge Server package.Affected if System is not running Synology DSM
-
Check DSM versionAccess DSM Control Panel > Updates and Maintenance, or run 'grep -i version /etc.defaults/VERSION' via SSH to retrieve the installed DSM version number.Affected if DSM version is prior to 1.76.0-0307
-
Confirm C2 Identity Edge Server package is installedIn DSM, navigate to Package Center > Installed, or check via CLI: 'cat /var/packages/C2IdentityEdgeServer/package.info' if the package directory exists.Affected if C2 Identity Edge Server package is installed and DSM version is below 1.76.0-0307
A system is affected if it runs Synology DSM with the C2 Identity Edge Server package installed and the DSM version is earlier than 1.76.0-0307.
