Highly critical
IMPACT:
Cross Site Scripting, Manipulation of data, System access
WHERE:
>From remote
SOFTWARE:
BSQ Sitestats 1.x (component for Joomla)
http://secunia.com/product/11854/
DESCRIPTION:
Secunia Research has discovered some vulnerabilities in the BSQ
Sitestats component for Joomla, which can be exploited by malicious
people to conduct cross-site scripting and SQL injection attacks, and
to compromise a vulnerable system.
1) Input passed to the "ip" form field parameter when performing an
IP Address Lookup is not properly sanitised before being returned to
the user. This can be exploited to execute arbitrary HTML and script
code in a logged in administrator's browser session in context of an
affected site.
2) Input passed to multiple parameters when importing the
ip-to-country.csv file is not properly sanitised before being used in
a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code when an administrator is tricked into
importing a malicious ip-to-country.csv file.
3) Input passed via the "HTTP Referer", the "HTTP User Agent", and
the "HTTP Accept Language" Header in bsqtemplateinc.php 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.
4) Input passed to the "baseDir" parameter in
components/com_bsq_sitestats/external/rssfeeds.php is not properly
verified before being used to include files. This can be exploited to
execute arbitrary PHP code by including files from local or external
resources.
Successful exploitation requires that "register_globals" is enabled.
The vulnerabilities have been confirmed in version 1.8.0. Other
versions may also be affected.
SOLUTION:
Update to version 2.2.1.
