The Google Search Appliance contains a flaw that allows a remote attacker to enumerate open services on other systems. The issue is due to the proxystylesheet parameter in the search request, which allows almost any host and port combination in the URL for a remote XSLT style sheet. The error message returned to the browser indicates whether a given host and port was available.
