Advisory Details:

High-Tech Bridge Security Research Lab discovered XSS vulnerability in 
SearchBlox, which can be exploited to perform Cross-Site Scripting attacks 
against the vulnerable web application administrators.

Input passed via the "menu2" HTTP GET parameter to "/searchblox/admin/main.jsp" 
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 scripting code in his browser in context of the 
vulnerable website.

A simple XSS exploit below uses the "alert()" JS function to display a box with 
"ImmuniWeb" word:

http://[host]/searchblox/admin/main.jsp?menu1=adm&menu2=%22%3E%3Cscript%3Ealert%28%27ImmuniWeb%27%29;%3C/script%3E
