TITLE:
CJ Web2Mail Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA16963

VERIFY ADVISORY:
http://secunia.com/advisories/16963/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
From remote

SOFTWARE:
CJ Web2Mail 3.x
http://secunia.com/product/5771/

DESCRIPTION:
Psymera has discovered some vulnerabilities in CJ Web2Mail, which can
be exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "name", "message", and "ip" parameters in
"thankyou.php", and the "emsg" parameter in "web2mail.php" isn't
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.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities have been confirmed in version 3.0. Other
versions may also be affected.

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

Set "register_globals" to "Off".

PROVIDED AND/OR DISCOVERED BY:
