DESCRIPTION:
Multiple vulnerabilities have been discovered in Exponent CMS, which
can be exploited by malicious people to conduct cross-site request
forgery attacks and disclose sensitive information.

1) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. create an arbitrary user with
administrative privileges if a logged-in administrative user visits a
malicious web site.

2) Input passed via the "controller" parameter to
content_selector.php (when "section" and "action" are set) is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources via
directory traversal sequences and URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

3) Input passed via the "file" parameter to
framework/modules/pixidou/download.php is not properly verified
before being used to download files. This can be exploited to
download arbitrary files from local resources via directory traversal
sequences.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 2.0.0 beta2.1. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified. Do not browse untrusted sites or follow untrusted links
while being logged-in to the application.

PROVIDED AND/OR DISCOVERED BY:
1) outlaw.dll
2-3) AutoSec Tools
