CVE-2022-3284
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 · uneditedDownload key for a file in a vault was passed in an insecure way that could easily be logged in M-Files New Web in M-Files before 22.11.12011.0. This issue affects M-Files New Web: before 22.11.12011.0.
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 confidenceIn M-Files New Web versions before 22.11.12011.0, download keys for vault files were transmitted via insecure methods (likely URL parameters) that get easily logged in server logs, browser history, and proxy logs. This exposes sensitive file access credentials through standard HTTP logging mechanisms.

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.
-
Check M-Files Server versionOpen M-Files Admin, go to the server node, and view the version information displayed in the general settings. Alternatively, check the installed version through Programs and Features in Windows Control Panel.Affected if The installed version is below 22.11.12011.0
-
Determine if New Web interface is enabledIn M-Files Admin, navigate to the vault settings or server configuration and look for the New Web (modern web interface) setting. This is typically found under Vault Properties or Server Settings.Affected if New Web interface is enabled and the version is below 22.11.12011.0
-
Review server access logs for download key exposureExamine IIS logs (typically in C:\inetpub\logs\LogFiles or custom log paths), M-Files server logs, or any proxy/firewall logs for URLs containing patterns like 'downloadkey', 'download', or vault file references with key parameters. Search for repeated alphanumeric strings in GET request URLs.Affected if Log entries contain URL parameters with vault file download keys that could expose file access credentials
You are affected if M-Files Server version is below 22.11.12011.0 and the New Web interface is in use, as download keys may have been transmitted insecurely and logged.

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 · scoped22.11.12011.0
Upgrade M-Files to version 22.11.12011.0 or later, which addresses the insecure key transmission. As a temporary measure, review and purge access logs that may contain exposed download keys.
22.11.12011.0
- Upgrade M Files Server to version 22.11.12011.0 or later
- After upgrading, verify that M-Files New Web is also updated to version 22.11.12011.0 or later
- Confirm the fix by testing file downloads in M-Files New Web and verifying the download key is no longer exposed in logs
