Vulnerability Description ---------------------------- Various components of the LiveZilla application are vulnerable to cross site scripting. An attacker can hijack an operator with cross site scripting. For example his cookie containing parts of the login information can be retrieved by the attacker that he can later use to login into the 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 triggered. The script code will be executed at the administrators chat website. Example XSS: '>> An attacker is also able to write HTML and script code into the admins 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 he can send HTML and script code instead of a text message. When the administrator later clicks into the archive section the HTML and script code will be executed. 5.
