CVE-2020-19961Public exploitNetwork attack vector

Database disclosure via unescaped cookie interpolation

Published Oct 14, 2021 · Updated Jul 9, 2026

SQL injection in zzcms 2019 subzs.php allows remote attackers to retrieve database data through a crafted zzcmscpid cookie. In showcookiezs(), the comma-separated zzcmscpid cookie value is concatenated directly into an id IN clause before query() executes it. The attack requires a reachable /zs/zs_list.php page and a crafted cookie; the published Boolean-response oracle demonstrates disclosure only, not data writes or code execution.
