| Title | SeaCMS 13.6 Code Injection |
|---|
| Description | SeaCMS 13.6 search.php with searchtype=5 substitutes user-controlled cascade filter values such as area/yuyan into template {if:...} expressions. The rendered template is processed by parseIf(), which evaluates conditions with PHP eval(). An unauthenticated attacker can execute short PHP expressions such as print`id`, resulting in remote command execution as the web server user. |
