DESCRIPTION:
Frank "brOmstar" Reissner has reported a vulnerability in EncapsBB,
which can be exploited by malicious people to compromise a vulnerable
system.

Input passed to the "root" parameter in "index_header.php" 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 reported in version 0.3.2_fixed. Other
versions may also be affected.

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