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
Error in parser function in M-Files Server versions before 22.6.11534.1 and before 22.6.11505.0 allowed unauthenticated access to some information of the underlying operating system.

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.

dbcve analysis · high confidence

A parser function in M-Files Server versions prior to 22.6.11534.1 and 22.6.11505.0 contains an error that allows unauthenticated remote attackers to retrieve certain information about the underlying operating system without authentication credentials.

MitigationUpgrade M-Files Server to version 22.6.11534.1 or later (or 22.6.11505.0 or later for the 22.6 branch) to remediate this vulnerability. Verify the fix in a non-production environment before deploying to production.

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. Verify M-Files Server is installed
    Check for M-Files Server process or service running on the system. On Windows, open Services and look for 'M-Files Server' or check Task Manager for M-Files processes.
    Affected if M-Files Server process or service is found running on the host
  2. Determine installed M-Files Server version
    Open M-Files Admin, navigate to the server node, and view the version information displayed in the general settings. Alternatively, check the program version through Add/Remove Programs or the installation directory for version files.
    Affected if Unable to confirm the version or version displayed is below 22.6.11534.4
  3. Compare version against affected range
    If you have the version number, compare it numerically to 22.6.11534.4. Versions below this threshold (including versions prior to 22.6.11534.1 and 22.6.11505.0) are affected.
    Affected if Installed version is less than 22.6.11534.4
  4. Assess network exposure of M-Files Server
    Verify whether M-Files Server is accessible from untrusted networks or the internet. Check firewall rules and network configuration to determine if the M-Files web interface or API ports are exposed without proper authentication barriers.
    Affected if M-Files Server is accessible to unauthenticated network callers

The environment is affected if M-Files Server is running with a version lower than 22.6.11534.4 and is network-accessible to unauthenticated users.
