III. PROOF OF CONCEPT
-------------------------

Cross site scripting
*********************

Vulnerability description
___________________________

This script is possibly vulnerable to Cross Site Scripting (XSS) attacks.

Cross site scripting (also referred to as XSS) is a vulnerability that allows an 
attacker to send malicious code (usually in the form of Javascript) to another user.
Because a browser cannot know if the script should be trusted or not, it will execute
the script in the user context allowing the attacker to access any cookies or session tokens retained by the browser. 

This vulnerability affects

/rus/about/community/unicolours/frame.wbp. (46)
