CVE-2021-30205Public exploitNetwork attack vector

Directory disclosure via unauthenticated orgtree endpoint

Published Jun 27, 2023 · Updated Dec 5, 2024

Incorrect authorization in DzzOffice 2.02.1_SC_UTF8 allows remote attackers to read department names and usernames through an HTTP request. The system orgtree endpoint returns organization-tree data when /index.php?mod=system&op=orgtree is requested without a logged-in session. The endpoint must be network-reachable; exploitation requires no account or user interaction and exposes directory information without changing it.
