CRITICAL:

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
3CX Phone System 6.x
http://secunia.com/advisories/product/20703/

DESCRIPTION:
Chris Castaldo has discovered some vulnerabilities in 3CX Phone
System, which can be exploited by malicious people to conduct
cross-site scripting attacks.

Input passed to the "fName" and "fPassword" form parameters in
login.php 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 the context of an affected site.

These vulnerabilities are confirmed in 3CX Phone System Free Edition
version 6.1793. Other versions may also be affected.

SOLUTION:
Update to version 7.0.
