Cross-student document disclosure via forced access flag
Published Jun 8, 2023 · Updated Jan 6, 2025
Incorrect authorization in Chamilo LMS 1.11.0 through 1.11.18 allows remote authenticated users to download another student's work. In main/work/work.lib.php, downloadFile passed true as getFile's force-access argument, so the authorization condition accepted nonowners when general access was allowed. Course enrollment and knowledge of another work document's ID are required; the reported consequence is disclosure of that document only.
