DESCRIPTION:
Nemesis Security Audit Group has discovered a vulnerability in
Website Generator, which can be exploited by malicious users to
bypass certain security restrictions.

Input passed to the "formname" parameter in process3.php isn't
properly sanitised before being used to create files. This can be
exploited by administrative users to create form files with the
".php" extension that contains PHP code.

Example:
formname=file.php%00

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been confirmed in version 3.3. Other versions
may also be affected.

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