CVE-2023-0383
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 · uneditedUser-controlled operations could have allowed Denial of Service in M-Files Server before 23.4.12528.1 due to uncontrolled memory consumption.
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 confidenceThis is a Denial of Service vulnerability in M-Files Server caused by uncontrolled memory consumption when processing user-controlled operations. Attackers can exploit this in versions prior to 23.4.12528.1 to exhaust server resources and make the service unavailable.

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.
-
Identify M-Files Server versionOpen 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
-
Confirm version comparisonCompare 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
-
Verify M-Files Server is runningCheck 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.
