CVE-2020-19822Public exploitNetwork attack vector

Authenticated PHP code execution via template parameters

Published Aug 26, 2021 · Updated Aug 4, 2024

Code injection in ZZCMS 2018 template_user.php allows remote authenticated users to execute arbitrary PHP code through ml and title parameters. The public record identifies the affected handler and parameters but does not disclose the exact PHP evaluation or file-write operation. High application privileges are required, and successful exploitation runs attacker-supplied PHP with the web application's privileges.
