Advisory Details:

High-Tech Bridge Security Research Lab discovered vulnerability in iTop, which 
can be exploited to perform Cross-Site Scripting (XSS) attacks against web 
application users. iTop is a critical application, which is used to cover the 
entire set of ITIL processes. Successful attack on this web application may 
result in critical information exposure, data loss, and even unauthorized 
access to network infrastructure. 

The vulnerability exists due to insufficient filtration of input-data passed 
via the "title" HTTP GET parameter to "/pages/ajax.render.php" script. A remote 
unauthenticated 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.

This vulnerability can be used in an advanced attack to compromise the web 
application and gain control over services within the local network. 

A simple exploit below will display a JS popup with "ImmuniWeb" word:

http://[host]/pages/ajax.render.php?operation=render_dashboard&dashboard_id=1&layout_class=DashboardLayoutOneCol&title=%3Cimg%20src=%22x%22%20onerror=javascript:alert%28%27ImmuniWeb%27%29;%3E

Solution:

Update to iTop 2.2.0-2459
