CVE-2023-2480
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 · uneditedMissing access permissions checks in M-Files Client before 23.5.12598.0 (excluding 23.2 SR2 and newer) allows elevation of privilege via UI extension applications
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 confidenceM-Files Client contains a missing access control vulnerability where UI extension applications can bypass permission checks, allowing authenticated users to perform actions beyond their authorized privileges. This enables local privilege escalation through malicious or improperly configured UI extensions.

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.
-
Verify M-Files Client installationCheck for M-Files installation directory in Program Files or Program Files (x86), or query the Windows registry under HKLM\SOFTWARE\M-Files for the installed productAffected if M-Files Client is found on the system
-
Determine installed M-Files versionLocate the M-Files client executable (typically in the M-Files installation folder) and view its file properties to obtain the version, or query the registry key HKLM\SOFTWARE\M-Files\CurrentVersionAffected if The version is lower than 23.5.12598.0 (or lower than 23.2 SR2)
-
Identify configured UI extensionsExamine the M-Files client configuration folder (typically found in %APPDATA%\M-Files\VaultApplications or within the vault structure) for any installed UI extension packages or add-insAffected if UI extension applications are present and configured in the M-Files environment
The environment is affected if M-Files Client version is below 23.5.12598.0 and UI extension applications are enabled or installed, as the vulnerability allows these extensions to bypass permission checks.
