DESCRIPTION:
Two vulnerabilities have been discovered in Ultimate PHP Board, which
can be exploited by malicious users to bypass certain security
restrictions and disclose sensitive information.

1) An error in the admin_restore.php script does not properly check
for access permissions before allowing access to the script. This can
be exploited to create and download the data backup and disclose
sensitive information or restore the data backup of  another
installation.

2) Input passed to the "file" parameter in admin_restore.php (when
"action" is set to "download") is not properly verified before being
used to read files. This can be exploited to download arbitrary files
from local resources via directory traversal sequences.

The vulnerabilities are confirmed in version 2.2.6. Other versions
may also be affected.

SOLUTION:
Restrict access to the admin_restore.php script (e.g. via .htaccess).
Edit the source code to ensure that input is properly verified.
