H D Moore has reported some vulnerabilities in Google Mini Search Appliance, which can be exploited by malicious people to conduct cross-site scripting attacks and potentially to compromise a vulnerable appliance.
1) Input passed to the "proxystylesheet" parameter isn't properly sanitised before being returned to the user in an error message. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) It is possible to enumerate open ports on other systems by providing the full URL containing hostname and port number to a vulnerability appliance and observing the error message.
Note: It is also possible to determine the existence of any file on a vulnerable appliance by providing the relative pathname of the file to the "proxystylesheet" parameter and observing the error message.
Solution: A patch is reportedly available from the vendor.
