CVE-2023-24834
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 · uneditedWisdomGarden Tronclass has improper access control when uploading file. An authenticated remote attacker with general user privilege can exploit this vulnerability to access files belonging to other users by modifying the file ID within URL.
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 confidenceWisdomGarden Tronclass learning management system contains an Insecure Direct Object Reference (IDOR) vulnerability in its file upload/handling functionality. An authenticated user with standard privileges can access files uploaded by other users by manipulating the file ID parameter in the request URL, bypassing proper authorization checks.

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 installed versionLocate the version number in the product about page, admin dashboard, or version configuration file. Common locations include the system administration panel or a /about/version endpoint.Affected if The version is less than 1.52.29198 or equals 2.3.2
-
Verify file upload functionality is accessibleConfirm that the file upload/attachment feature is available to standard authenticated users. Check if users can upload documents, images, or other files within the system.Affected if Standard users can access the file upload feature and view a file listing or repository
-
Test file access authorizationAs a standard user, attempt to access a file by manipulating the file ID parameter in the request URL. Compare file IDs from your own uploaded files against files known to be uploaded by other users, then try accessing the latter using your session.Affected if You can successfully view files belonging to other users by changing the file ID in the request, indicating missing authorization checks
You are affected if your installed version matches the vulnerable range and the file access feature permits cross-user file retrieval without proper authorization.

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 data1.52.29198
Implement proper server-side authorization validation to ensure users can only access files they own or have been explicitly granted permission to view, regardless of submitted file IDs.
