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. Identify M-Files Server version
    Open M-Files Admin and navigate to the server node, or check Windows Programs and Features for M-Files Server entry. The version is displayed as a four-part number.
    Affected if The installed version is less than 23.4.12528.1
  2. Confirm version comparison
    Compare your installed version number against 23.4.12528.1 using standard version comparison (each numeric segment must be >= the corresponding segment in 23.4.12528.1 to be unaffected).
    Affected if Any segment of your version is lower than the corresponding segment in 23.4.12528.1
  3. Verify M-Files Server is running
    Check that the M-Files Server service is active and accepting user connections, either through M-Files Admin status or Windows Services console.
    Affected if The server is running a vulnerable version and is processing user-controlled operations.

If the installed M-Files Server version is below 23.4.12528.1 and the service is operational, the environment is affected by this memory exhaustion vulnerability.
