CVE-2025-40661
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/selection.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 · high confidenceAn IDOR vulnerability in DM Corporative CMS allows unauthorized access to the private administrative area via the /administer/selectionnode/selection.asp endpoint by manipulating the 'option' parameter to values 0, 1, or 2. This bypasses proper authorization controls, enabling attackers to access restricted administrative functions without authentication.

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.
-
Confirm DM Corporative CMS installationInspect the web server for the presence of DM Corporative CMS by checking application directories, headers, or source code references to 'Acc Dm Corporative Cms' or 'DM Corporative CMS'.Affected if The application is identified as DM Corporative CMS.
-
Determine installed versionLocate version information in the CMS installation, typically found in a version file, about page, header/footer, or configuration file. Compare the version to the affected range.Affected if The installed version is earlier than 2025.01.
-
Verify vulnerable endpoint existsCheck if the file /administer/selectionnode/selection.asp exists in the web application directory.Affected if The selection.asp file exists in the /administer/selectionnode/ path.
-
Test unauthenticated access to admin areaSend an HTTP GET request to /administer/selectionnode/selection.asp with an 'option' parameter set to 0, 1, or 2 without providing authentication credentials. Examine the response for successful access to administrative functions.Affected if The endpoint returns administrative content or grants access to restricted areas without authentication.
A user is affected if DM Corporative CMS version is earlier than 2025.01 AND the vulnerable /administer/selectionnode/selection.asp endpoint is accessible without authentication by manipulating the 'option' parameter.

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 server-side authorization checks to verify user permissions before granting access to private areas. Validate that the authenticated user has appropriate privileges for the requested option value.
2025.01
- Upgrade Dm Corporative CMS to version 2025.01 or later to resolve the IDOR vulnerability in /administer/selectionnode/selection.asp
- After upgrading, verify that the option parameter no longer allows unauthorized access to private areas
- Confirm the fix by testing with option=0, option=1, and option=2 parameters to ensure proper authorization controls are enforced
