CVE-2025-40659
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 · uneditedAn Insecure Direct Object Reference (IDOR) vulnerability has been found in DM Corporative CMS. This vulnerability allows an attacker to access the private area setting the option parameter equal to 0, 1 or 2 in /administer/selectionnode/framesSelectionNetworks.asp.
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 confidenceIDOR vulnerability in DM Corporative CMS allows unauthenticated access to private administrative areas by manipulating the 'option' parameter (values 0, 1, or 2) in the /administer/selectionnode/framesSelectionNetworks.asp endpoint. The application fails to validate user authorization before granting access to sensitive frames or data based on this parameter.

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 DM Corporative CMS installationCheck for the presence of the application by locating the /administer/ selectionnode/framesSelectionNetworks.asp file or check the web server for DM Corporative CMS bannersAffected if The application file exists on the server and responds to requests
-
Determine the installed versionCheck the application version information, typically found in the CMS admin panel, a version file, or the HTTP server headers for 'Acc Dm Corporative Cms'Affected if The installed version is any version prior to 2025.01
-
Verify the vulnerable endpoint existsAttempt to access the /administer/selectionnode/framesSelectionNetworks.asp endpoint via HTTP GET requestAffected if The endpoint responds with any content (200 OK or similar status)
-
Test for IDOR via option parameterSend unauthenticated HTTP GET requests to framesSelectionNetworks.asp with 'option=0', 'option=1', and 'option=2' parameters and observe if private administrative frames or data are returned without loginAffected if The endpoint returns administrative frames, sensitive data, or restricted content without requiring authentication or authorization
A system is affected if DM Corporative CMS version is below 2025.01 AND the framesSelectionNetworks.asp endpoint is accessible and returns private administrative content when the 'option' parameter (0, 1, or 2) is manipulated without authentication.

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 authorization checks on the framesSelectionNetworks.asp endpoint to verify user permissions before allowing access to private areas. Additionally, use indirect object references (mapping internal IDs to random tokens) rather than exposing direct parameter values.
2025.01
- 1. Identify the current version of DM Corporative CMS installed on the system
- 2. Create a complete backup of the CMS database and all files
- 3. Download DM Corporative CMS version 2025.01 or later from the official vendor
- 4. Deploy the upgrade following the vendor's standard upgrade procedure
- 5. After upgrading, verify that the vulnerability is fixed by attempting to access the affected endpoint (/administer/selectionnode/framesSelectionNetworks.asp) with the option parameter set to 0, 1, or 2 - it should no longer allow unauthorized access
- 6. Confirm that legitimate authorized access still functions correctly
