Various components of the LiveZilla application are vulnerable to cross

administrator website without entering username and password. When the  
attacker enters the script code as the name before connecting and  
calling the administrator the cross site scripting vulnerability is  
The script code will be executed at the administrators chat website.

visitor information panel, this allows to completely modify the website  
the administrator is viewing and conduct phishing attacks.  
Another Cross Site Scripting vulnerability exists in the view archive  
section of the windows application.  
An attacker can start a chat session that the admin has to accept then

and script code will be executed.
