Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper neutralization of special elements used in an SQL command ('SQL Injection') vulnerability in IOModule.EnumLog webapi component in Synology Surveillance Station before 9.2.0-11289 and 9.2.0-9289 allows remote authenticated users to read database containing non-sensitive information and conduct limited denial-of-service attacks via unspecified vectors.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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. Confirm Synology Surveillance Station is installed
    Check if the Synology Surveillance Station package is installed on the Synology NAS. This can be done via the Synology Package Center interface, or by accessing the system via SSH and checking for the surveillance station package directory (typically under /var/packages/SurveillanceStation).
    Affected if The package is not installed or no surveillance station installation is found.
  2. Identify installed Surveillance Station version
    Access the Surveillance Station web interface, go to Menu > System > General > About to view the exact version number. Alternatively, check via SSH by running: cat /var/packages/SurveillanceStation/etc/ssapp/version or checking the package info via Synology CLI.
    Affected if The installed version is lower than 9.2.0-9289 or lower than 9.2.0-11289.
  3. Verify the IOModule webapi endpoint is accessible
    Test access to the Surveillance Station webapi by attempting to reach an endpoint such as https://[nas-ip]:[port]/webapi/entry.cgi?api=SYNO.SurveillanceStation.IOModule.EnumLog&method=List. The exact path may vary based on DSM configuration.
    Affected if The webapi endpoint responds and accepts requests (even if authentication fails, the endpoint exists).
  4. Confirm remote authentication is enabled
    Check if remote users can authenticate to Surveillance Station by verifying that local user accounts or domain users have Surveillance Station access permissions. Go to Surveillance Station > Settings > User and Permission to review permitted users.
    Affected if Remote authentication is permitted for non-admin or non-local-only users who can access Surveillance Station.

You are affected if Synology Surveillance Station is installed and the installed version is below 9.2.0-9289 (or below 9.2.0-11289 depending on your specific build) AND the IOModule webapi is accessible with remote authentication enabled.
