CVE-2019-12351Public exploitNetwork attack vector

Arbitrary SQL query execution via unfiltered id parameter

Published Jun 2, 2022 · Updated Aug 4, 2024

SQL injection in ZZCMS 2019 allows remote attackers to execute arbitrary database queries through the dl/dl_print.php id parameter. Lines 76–80 treat an array-form id ending in a comma as SQL syntax and concatenate it without quoting or filtering, enabling a UNION payload. The published proof of concept sends unauthenticated POST data and retrieves the database version; broader database impact depends on database permissions.
