DESCRIPTION:
Secunia Research has discovered a vulnerability in Pinnacle
ShowCenter, which can be exploited by malicious people to conduct
cross-site scripting attacks.

Invalid input passed to the "Skin" parameter in "SettingsBase.php"
isn't sanitised before being returned to the user in a error page.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site by tricking the
user into visiting a malicious web site or follow a specially crafted
link.

Example:
http://[host]:8000/ShowCenter/SettingsBase.php?Skin=[code]

The vulnerability has been confirmed in version 1.51 build 121. Other
versions may also be affected.

SOLUTION:
No vendor solution is currently available. The vendor has been
contacted multiple times, but has not responded.
