CVE-2023-6554Network attack vector

Exam-answer disclosure via unprotected admin folder

Published Jan 11, 2024 · Updated Jun 20, 2025

Missing authorization in the TCExam admin folder before 15.1.0 allows remote authenticated users to download exam answers. The application serves protected files from that folder when requests are not blocked by an external authorization layer; public sources identify no specific handler or file path. The condition requires network access to the admin folder without external protection, and the documented consequence is read-only disclosure of exam answers.
