CVE-2023-44847Public exploitNetwork attack vector

Authenticated code execution via unsafe PHP write

Published Oct 10, 2023 · Updated Sep 19, 2024

Code injection in SeaCMS 12.8 allows remote authenticated users to execute arbitrary PHP code through the admin_Weixin.php component. The action=set handler concatenates unvalidated WeChat-setting values into data/admin/weixin.php, causing attacker-supplied PHP syntax to be saved and executed when that file is requested. Administrative access is required; successful exploitation runs code with the web server's privileges and can read, alter, or interrupt the hosted service.
