Advisory Details:

High-Tech Bridge Security Research Lab discovered an XSS vulnerability in 
Revive Adserver (formerly known as OpenX Source), which can be exploited to 
perform Cross-Site Scripting attacks against administrators of the vulnerable 
application leading to total compromise of the Ads platform. 

The vulnerability allows to steal cookies, sessions and credentials stored in 
the browser, as well as to perform more complicated attacks such as phishing 
and drive-by attacks.


1) Cross-Site Scripting (XSS) in Revive Adserver: CVE-2014-8793

1.1 Input passed via the "refresh_page" HTTP GET parameter to 
"/www/admin/report-generate.php" script is not properly sanitised before being 
returned to the user. A remote attacker can trick a logged-in administrator 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 will show a pop-up window with "ImmuniWeb" word 
inside after user clicks on the following link:

http://[host]/www/admin/report-generate.php?submit_type=change&refresh_page=%3C/script%3E%3Cscript%3Ealert%28%27ImmuniWeb%27%29;%3C/script%3E


-----------------------------------------------------------------------------------------------
