CVE-2023-6117
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 · uneditedA possibility of unwanted server memory consumption was detected through the obsolete functionalities in the Rest API methods of the M-Files server before 23.11.13156.0 which allows attackers to execute DoS attacks.
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 · moderate confidenceMemory consumption vulnerability in M-Files server REST API where obsolete functionalities allow attackers to trigger excessive memory allocation via specially crafted API requests, leading to denial of service. The vulnerability is exploitable remotely without authentication and affects versions prior to 23.11.13156.0.

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.
-
Determine M-Files Server versionAccess the M-Files Server administration interface or check the installed software version through the system control panel, registry, or M-Files administrative toolsAffected if The installed version is 23.11.13156.0 or earlier (any version prior to 23.11.13156.0)
-
Verify REST API is accessibleConfirm that the M-Files REST API endpoint is exposed and reachable on the server (typically at /MFilesServerAPI/ or similar paths)Affected if The REST API is enabled and accessible over the network without authentication
-
Check network exposureDetermine if the M-Files Server REST API ports (default HTTP/HTTPS ports) are exposed to untrusted networks or the internetAffected if The REST API is reachable from untrusted network segments or directly from the internet
-
Review API request patternsMonitor server logs or API access logs for unusually high memory consumption or failed request patterns that may indicate exploitation attemptsAffected if The server exhibits high memory usage or API request failures consistent with memory exhaustion from crafted requests
A user is affected if their M-Files Server version is 23.11.13156.0 or earlier AND the REST API is enabled and accessible, particularly from untrusted networks.

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 · scopedUpgrade M-Files server to version 23.11.13156.0 or later to remove the obsolete REST API functionalities. Consider implementing rate limiting or API request monitoring as additional defensive measures until the patch is applied.
M Files Server 23.11.13156.0 or later
- Upgrade M Files Server to version 23.11.13156.0 or later
- After upgrade, verify the Rest API is functioning correctly
- Monitor server memory consumption to confirm the remediation
