DESCRIPTION:
Kacper has discovered a vulnerability in Php Blue Dragon CMS, which
can be exploited by malicious people to compromise a vulnerable
system.

Input passed to the "vsDragonRootPath" parameter in
public_includes/pub_popup/popup_finduser.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 vulnerability has been confirmed in version 2.8.0. Other versions
may also be affected.

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