测试环境:discuz X1.5+nginx 1.0

漏洞文件source/function/function_core.php,

代码:

$_G['setting']['domain']['app']['default'] && $content = preg_replace("/<a href=\"([^\"]+)\"/e", "rewriteoutput('site_default', 0, '".$_G['setting']['domain']['app']['default'].$port.$_G['siteroot']."', '\\1')", $content);

利用代码:
