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 checks

Work through these to decide whether this CVE applies to you.

  1. Check DSM version
    Log into DSM and go to Control Panel > System > System Information, or run `cat /etc/VERSION` via SSH to retrieve the exact DSM build number
    Affected if The installed version is lower than 6.2.4-25553 (build number below 25553)
  2. Confirm remote access is enabled
    In DSM Control Panel > Network > Network Settings, verify if remote access features such as QuickConnect or external network access are enabled
    Affected if Remote network access to the DSM interface is permitted, allowing external attackers to reach the login page
  3. Verify authentication methods
    Go to Control Panel > User & Group to confirm that user accounts exist and can log into the DSM web interface
    Affected if Any authenticated user account exists in DSM, as the vulnerability affects remote authenticated users
  4. Check task manager accessibility
    In DSM, navigate to the Task Scheduler (Control Panel > Task Scheduler) to confirm the task management component is accessible
    Affected if The Task Scheduler feature is available and enabled in the DSM installation

You are affected if your DSM version is below 6.2.4-25553 and the DSM interface is accessible to remote authenticated users.
