Our vulnerability scanner found the following "XSS vulnerability" - Can someone speak to the validity of this or why it might be a false positive? Any assistance would be greatly appreciated.

Injected into the "CiHiliteType" URL parameter (Using method GET) in https://[splunk_server_ip]/null.htw?CiWebHitsFile=/<script>xss</script>.aspx&CiRestriction=none&CiHiliteType=Full by changing the URL to https://[splunk_server_ip]/null.htw?CiWebHitsFile=/<script>xss</script>.aspx&CiRestriction=none&CiHiliteType=\"><script>248484113

2: var hashTag = '', hashPos = document.location.href.indexOf('#');
3: if (hashPos > -1) { hashTag = document.location.href.substr(hashPos...
4: ...iHiliteType=\\"><script>248484113" + hashTag;

Good day!

In the future, please report security concerns via support if you have a support agreement or via the Splunk Product Security Portal http://www.splunk.com/page/securityportal

This is a false positive for 2 reasons:

This request is generating a 303 redirection page and there are no supported browsers that we are aware of that interpret Javascript in this context.
The context that the issue is a Javascript string parsing context. The input string cannot escape the context due to the presence of other encoding rules.

Thanks for the report and please use the portal in the future in case this isn't a false positive issue and we need to deliver a fix to you and other customers!
