Authenticated file disclosure via unsanitized path argument
Published Apr 17, 2026 · Updated Apr 17, 2026
Path traversal in JTBC CMS 5.0.3.6 allows remote authenticated users to read server files through the Code Endpoint. The manage.php handler constructs a filesystem pathname from the path argument without neutralizing traversal elements that escape its restricted directory. Exploitation requires an authenticated remote session and exposes files readable by the CMS process, with no reported write or service-interruption impact.
