Xss attack Details

• XSS Shell is a cross-site scripting backdoor into the victim's browser which enables an attacker to issue commands and receive responses. 
• During a normal XSS attack an attacker only has one chance to control a victim's browser; however, the XSS Shell keeps the connection between the attacker and the victim open to allow the attacker to continuously manipulate the victim's browser. 
• XSS Shell works by setting up an XSS Channel, an AJAX application embedded into the victim's browser, that can obtain commands and send back responses. 
• To enable the XSS Shell an attacker needs to inject the XSS Shell's Javascript reference by utilizing a XSS flaw on a website. 
• Once the victim's browser is infected with the XSS Shell and the XSS Channel is created, the attacker can issue instructions to the infected browser. 
• Also, the Attacker can use a XSS Tunnel to transfer HTTP traffic through the XSS Channel and the victim's browser; in turn, exploiting the victim's credentials to bypass authentications and IP Restrictions. 
• The XSS Tunnel is a HTTP Proxy that sits on an attacker's computer, and any tool that is configured to use it will tunnel its traffic through the XSS Channel.
