TITLE:
Google Mini Search Appliance Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA17644

VERIFY ADVISORY:
http://secunia.com/advisories/17644/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

OPERATING SYSTEM:
Google Mini Search Appliance
http://secunia.com/product/6166/

DESCRIPTION:
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.

2) XSLT style sheets provided by a user using a URL in the
"proxystylesheet" parameter isn't properly sanitised before being
used. This can be exploited to execute arbitrary Java class methods
on a vulnerable appliance via a malicious XSLT style sheet. It is
also possible to conduct cross-site scripting attacks by including
malicious Javascript in the style sheet.

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.
