TITLE:
Php Blue Dragon CMS Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA22031

VERIFY ADVISORY:
http://secunia.com/advisories/22031/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
Php Blue Dragon CMS 2.x
http://secunia.com/product/9942/

DESCRIPTION:
Kacper has discovered some vulnerabilities in Php Blue Dragon CMS,
which can be exploited by malicious people to conduct cross-site
scripting and SQL injection attacks, and compromise a vulnerable
system.

1) Input passed to the "m" parameter in index.php isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) Input passed to the "m" parameter in index.php isn't properly
sanitised before being returned to the user via a SQL error message.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

3) Input passed to the "phpExt" parameter in pbd_engine.php isn't
properly verified, before it is used to include files. This can be
exploited to include arbitrary files from local resources.

Successful exploitation requires that "register_globals" is enabled.

This can further be exploited to include arbitrary PHP script code
injected into log files (e.g. input passed when registering).

The vulnerabilities have been confirmed in version 2.8.0 and have
also been reported in version 2.9.1 (BETA). Other versions may also
be affected.

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