CVE-2025-40662
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 · uneditedAbsolute path disclosure vulnerability in DM Corporative CMS. This vulnerability allows an attacker to view the contents of webroot/file, if navigating to a non-existent file.
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 confidenceDM Corporative CMS fails to properly handle requests for non-existent files, exposing absolute file paths in error messages or responses. An attacker can manipulate file paths to trigger this disclosure, potentially revealing sensitive system information such as full server paths that aid in further exploitation.

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 if Acc Dm Corporative Cms is installedExamine the web application banners, footers, or source code for references to 'DM Corporative CMS' or 'Acc Dm Corporative Cms'. Check the application directory structure for characteristic files.Affected if The application is identified as Acc Dm Corporative Cms
-
Determine the installed versionLook for version information in the application admin panel, README files, or in the HTML source (meta tags, comments). Compare your installed version against the affected range of versions prior to 2025.01.Affected if The installed version is lower than 2025.01
-
Test for path disclosure on non-existent file requestsSend HTTP requests to the web server for files that do not exist, such as /nonexistentfile123.php or /invalidpath/test.html. Inspect the HTTP response body and any error pages returned.Affected if The error response contains absolute file system paths (e.g., /var/www/, C:\inetpub\, or similar full paths)
The system is affected if it runs Acc Dm Corporative Cms version prior to 2025.01 and discloses absolute file paths in responses when requesting non-existent files.

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 · scoped2025.01
Implement proper error handling that returns generic error messages without exposing file system paths. Validate file existence before processing and configure the application to handle 404 errors without path disclosure.
2025.01
- 1. Backup the current DM Corporative CMS installation and database
- 2. Download the latest version (2025.01 or later) from the official vendor
- 3. Replace the existing CMS files with the new version
- 4. Verify that custom configurations are preserved or re-applied if needed
- 5. Test the application to ensure functionality remains intact
- 6. Confirm the path disclosure vulnerability is resolved by attempting to access a non-existent file and verifying no absolute paths are exposed
