Summary

PlayEdu through 2.3 contains a missing authorization vulnerability in the CourseController that allows authenticated students to access department-restricted courses by omitting the department visibility check. Attackers can enumerate sequential course and attachment IDs via the course details and attachment download endpoints to obtain course structure and attachment files from other departments.

Risk Assessment

Leakage of training materials and attachment files from other departments can lead to a breach of confidentiality of internal organizational content. The risk affects the protection of intellectual property and internal data.

Recommendation

Upgrade PlayEdu beyond 2.3 as soon as a fixed version is available, and enforce server-side department visibility checks in CourseController. Consider auditing logs for unusual enumeration of course and attachment IDs.
