CVE-2025-41346
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 · uneditedFaulty authorization control in software WinPlus v24.11.27 by Informática del Este that allows another user to be impersonated simply by knowing their 'numerical ID', meaning that an attacker could compromise another user's account, thereby affecting the confidentiality, integrity, and availability of the data stored in the application.
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 confidenceWinPlus v24.11.27 contains a broken authorization vulnerability where the application relies on a user's numerical ID for identity verification without proper session validation. An attacker can impersonate any user by simply submitting another user's numerical ID in requests, bypassing all authentication controls.

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 WinPlus versionCheck the installed WinPlus version number. Look in the application about page, software inventory, or version file typically found in the program directory.Affected if Version is exactly 24.11.27
-
Identify user identification method in requestsInspect HTTP requests or API calls sent by the application, particularly for sensitive operations. Look for parameters that contain numerical user IDs in the request body, headers, or URL.Affected if Requests contain client-supplied numerical user ID parameters for identity context
-
Check session token implementationExamine how the application handles authentication sessions. Review the authentication mechanism to see if session tokens are validated server-side or if the application relies primarily on user-supplied ID values.Affected if Session tokens are not validated server-side or are missing for user context verification
-
Test authorization boundaryCapture a legitimate request containing your own user ID, then modify the numerical ID parameter to another user's ID value and observe if the application accepts the impersonation.Affected if Application accepts requests with different user IDs without re-validating the session
-
Review sensitive endpoint protectionAudit endpoints that perform privileged or sensitive operations. Determine if these endpoints verify the session matches the requested user ID or only trust the ID provided in the request.Affected if Sensitive endpoints rely on client-supplied numerical IDs without session binding verification
You are affected if running WinPlus version 24.11.27 AND the application uses numerical user IDs in requests without proper server-side session validation.

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.
From vendor dataImplement robust session-based authentication using secure, non-predictable session tokens with server-side validation. All sensitive operations must verify the authenticated session matches the requested user context, not rely on client-supplied numerical identifiers.
