DESCRIPTION:
Multiple vulnerabilities have been discovered in eoCMS, which can be
exploited by malicious users to conduct script insertion attacks, and
by malicious people to disclose potentially sensitive information and
conduct SQL injection attacks.

1) The application fails to correctly sanitise user supplied input
via BBCode. This can be exploited to insert arbitrary HTML and script
code, which will get executed in a user's browser session in context
of an affected site when the malicious data is being viewed.

2) Input passed via the "eocms" Cookie parameter is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

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

3) Input passed via the "lang" parameter to index.php is not properly
verified before being used to include files. This can be exploited to
include certain files from local resources via directory traversal
sequences.

4) Input passed via the "theme" parameter to index.php 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.

The vulnerabilities are confirmed in version 0.9.04. Other versions
may also be affected.

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