====================================================================== 
4) Description of Vulnerability

Secunia Research has discovered some vulnerabilities in the BSQ
Sitestats component for Joomla, which can be exploited by malicious
people to conduct script insertion or SQL injection attacks.

1) Input passed via the "HTTP Referer" Header is not properly 
sanitised before being used. This can be exploited to insert arbitrary
HTML and script code, which is executed in an administrative user's
browser session in context of an affected site when the site
statistics are viewed.

2) Input passed via the URI string is not properly sanitised before
being used in SQL queries. This can be exploited to manipulate SQL
queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is disabled.

====================================================================== 
5) Solution 

Update to version 2.2.2.

====================================================================== 
6) Time Table 

28/09/2006 - Vendor notified.
