Chris Brockmeier commented on SOLR-3419:
----------------------------------------

There is a code fragment above (Attached) that possibly identifies a solution for this.   Are you going to update the product for this?
I also attached an Accunetix Web Scan to display the issue.

> There's no filtering of the wrapper function name passed to the solr search service
> If the name of the wrapper function passed to the solr query service is the following string - 
> %3C!doctype%20html%3E%3Chtml%3E%3Cbody%3E%3Cimg%20src=%22x%22%20onerror=%22alert%281%29%22%3E%3C/body%3E%3C/html%3E
> solr passes the string back as-is which results in an XSS attack in browsers like IE-7 which perform mime-sniffing. In any case, the callback function in a jsonp response should always be sanitized - http://stackoverflow.com/questions/2777021/do-i-need-to-sanitize-the-callback-parameter-from-a-jsonp-call
