Joomla Car Manager Component "msg" Cross-Site Scripting Vulnerability

SECUNIA ADVISORY ID:
SA37882

VERIFY ADVISORY:
http://secunia.com/advisories/37882/

DESCRIPTION:
Fl0riX has reported a vulnerability in the Car Manager component for
Joomla, which can be exploited by malicious people to conduct
cross-site scripting attacks.

Input passed to the "msg" parameter in index.php (when "option" is
set to "com_carman") is not properly sanitised before being returned
to the user. This can be exploited to execute arbitrary HTML and
script code in a user's browser session in context of an affected
site.

The vulnerability is reported in version 2.0.5. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
