TITLE:
REDAXO "REX[INCLUDE_PATH]" File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA20395

VERIFY ADVISORY:
http://secunia.com/advisories/20395/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
REDAXO 3.x
http://secunia.com/product/10298/

DESCRIPTION:
beford has discovered some vulnerabilities in REDAXO, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "REX[INCLUDE_PATH]" parameter in multiple files
is not properly verified before being used to include files. This can
be exploited to execute arbitrary PHP code by including files from
local or external resources.

Affected files:
redaxo/include/addons/image_resize/pages/index.inc.php
redaxo/include/addons/import_export/pages/index.inc.php
redaxo/include/addons/stats/pages/index.inc.php
redaxo/include/addons/simple_user/pages/index.inc.php (only in
version 3.0)
redaxo/include/addons/simple_shop/pages/index.inc.php (only in
version 3.0)

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities have been confirmed in version 3.0, 3.1, and 3.2.
Other versions may also be affected.

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