CVE-2023-24834Network attack vector

Cross-user file disclosure via modifiable file IDs

Published Mar 27, 2023 · Updated Feb 19, 2025

Improper access control in WisdomGarden TronClass ilearn 2.3.2 allows remote authenticated users to read other users' uploaded files. The upload-file retrieval path accepts a file ID from the URL and returns the referenced file without verifying that it belongs to the requesting user. Any general-privilege account can substitute another file ID; the reported consequence is cross-user file disclosure, not file modification or service interruption.
