CVE-2022-40443Public exploitNetwork attack vector

Installation-path disclosure via double-slash request

Published Sep 22, 2022 · Updated May 27, 2025

Absolute path traversal in ZZCMS 2022 allows remote attackers to disclose the application's installation path via an unauthenticated GET request. The /one/siteinfo.php endpoint processes a path changed to //one/siteinfo.php and returns an error containing the application's absolute filesystem location. No account or user interaction is required, and the demonstrated consequence is limited to disclosure of the server-side installation path.
