Technical details
The vulnerability is a code injection flaw in the fetch function of WTCMS's index.php endpoint. An attacker can manipulate the "content" parameter in a GET request to inject arbitrary PHP code without authentication. The injected code is executed server-side, allowing an attacker to write files, execute system commands, and achieve remote code execution. The attack requires only network access to the vulnerable endpoint and no authentication is necessary. A public proof-of-concept exploit exists that writes a PHP file to the server and executes arbitrary system commands. The vendor was contacted but did not respond, and no patch has been released.
