Advisory Details:

High-Tech Bridge Security Research Lab discovered vulnerability in Open Classifieds, which can be exploited to perform Cross-Site Scripting (XSS) attacks.

1) Cross-Site Scripting (XSS) in Open Classifieds: CVE-2014-2024
The vulnerability exists due to insufficient sanitisation of user-supplied data passed via the URI to "/shared-apartments-rooms/" URL. A remote attacker can trick a logged-in user to open a specially crafted link and execute arbitrary HTML and script code in browser in context of the vulnerable website.
The exploitation example below uses the JavaScript "alert()" function to display "immuniweb" word:
http://[host]/shared-apartments-rooms/</title><script>alert(%22immuniweb%22) </script>
