CVE-2023-0382
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 · high confidenceThis is a Denial of Service vulnerability in M-Files Server caused by uncontrolled memory consumption. User-controlled operations allow attackers to exhaust server memory resources, rendering the service unavailable.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 if M-Files Server is installedLook for the M-Files Server service in Windows Services (services.msc) named 'M-Files Server', or check for the installation directory (typically C:\Program Files\M-Files or C:\Program Files (x86)\M-Files).Affected if M-Files Server service or installation directory is found on the system
-
Retrieve the installed M-Files Server versionOpen Windows Services, locate the 'M-Files Server' service, right-click and select Properties. The version may be shown in the 'Path to executable' or check the file version of MFilesServer.exe in the installation bin folder. Alternatively, access M-Files Admin and check the server version from the vault properties.Affected if Version cannot be determined or is lower than 23.4.12528.1
-
Compare version against the affected rangeIf you obtained a version number, compare it numerically to 23.4.12528.1. Any version below 23.4.12528.1 (e.g., 23.3.x, 23.2.x, earlier releases) falls within the affected range.Affected if Installed version is below 23.4.12528.1
The environment is affected if M-Files Server is installed with a version lower than 23.4.12528.1, as this allows user-controlled operations to exhaust server memory and cause denial of service.

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.
