CVE-2023-2180Public exploitNetwork attack vector

Unauthenticated file disclosure via unvalidated download path

Published May 15, 2023 · Updated Jan 24, 2025

Path traversal in Kiwiz for WooCommerce 2.1.3 and earlier allows remote attackers to read arbitrary server files without authentication. The public concat-pdf.php endpoint Base64-decodes the file_name parameter and uses the resulting path for a download without validating traversal sequences. A crafted request can disclose files readable by the PHP process; PHAR deserialization additionally requires an attacker-controlled file already on the server.
