CVE-2023-1398Public exploitNetwork attack vector

Authenticated upload-directory escape via crafted filedir

Published Mar 14, 2023 · Updated Aug 2, 2024

Path traversal in TeaCMS 2.0 allows remote authenticated users to escape the intended upload directory through /admin/upload. The endpoint accepts a crafted ../filedir path, but the public report does not identify the responsible function or disclose whether it reads, writes, or deletes the resolved path. Low-privileged authentication is required; the documented consequence is filesystem path escape, while the resulting file operation remains undisclosed.
