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.

http://[host]/shared-apartments-rooms/</title><script>alert(%22immuniweb%22)</script>
