CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
HOT (Hot Open Tickets)

DESCRIPTION:
Kacper has discovered a vulnerability in Hot Open Tickets, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed to the "CLASS_PATH" parameter in various scripts in the
"admin" and "class" directories isn't properly verified, before it is
used to include files. This can be exploited to include arbitrary
files from external and local resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in version 11012004_ver2f. Other
versions may also be affected.

SOLUTION:
Set "register_globals" to "Off" for this application (e.g. with a
.htaccess file).

PROVIDED AND/OR DISCOVERED BY:
