Original article: http://www.davidsopas.com/2008/09/phpadult-cms-exploit/ phpAdultSite CMS is a PHP-based content management system for a adult pay site that fully supports MySQL. The code, layout, graphics of phpAdultSite are consistent through every single page of your site. It costs between $400 to $1100 depending on the license. I found that this script is vulnerable to a couple of topics. After no reply of this CMS vendors, send about two emails 1 week ago, I decided going to full disclosure. The problem exists on results_per_page variable. If it returns false, it gives a DB Error output on our browser, showing up path disclosure, sql statments that may lead to sql injections and also, it executes XSS attacks. PoC: index.php?&results_per_page=50' index.php?&results_per_page=50"><script type="text/javascript">alert(/XSS vuln by DavidSopas.com/)</script> It can be fixed with the sanitize of the variable.
