Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Synology CardDAV Server is installedCheck your Synology NAS for the CardDAV Server package. This can be done via Package Center in the Synology DSM interface, or by searching for CardDAV-related processes or installed packages on the NAS filesystem.Affected if CardDAV Server package is installed on the system
-
Determine the installed CardDAV Server versionAccess the Synology DSM interface, open Package Center, locate the CardDAV Server package, and view its version information. Alternatively, use the command line to query the installed package version if available.Affected if The installed version is lower than 6.0.10-0153
-
Verify the webapi component is accessibleCheck if the CardDAV Server webapi endpoint is exposed and accessible. This typically involves verifying network accessibility of the CardDAV Server web interface or API endpoints.Affected if The webapi component is exposed and accessible over the network
Your environment is affected if Synology CardDAV Server is installed with a version lower than 6.0.10-0153 and the webapi component is accessible to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.0.10-0153
Update to Synology CardDAV Server version 6.0.10-0153 or later. As a secondary measure, review and restrict CardDAV Server access to only necessary authenticated users until the patch can be applied.
CardDAV Server version 6.0.10-0153 or later
- Log into your Synology NAS using your admin credentials
- Open the Synology DiskStation Manager (DSM) interface
- Navigate to Package Center
- Locate CardDAV Server in the list of installed packages
- Click on CardDAV Server and select 'Update' to install the latest available version
- Verify that the installed version is 6.0.10-0153 or later
- After updating, ensure that CardDAV Server is functioning normally
