TITLE:
Gallery "stepOrder[]" Local File Inclusion Vulnerability

SECUNIA ADVISORY ID:
SA19175

VERIFY ADVISORY:
http://secunia.com/advisories/19175/

CRITICAL:
Highly critical

IMPACT:
Exposure of sensitive information, System access

WHERE:
>From remote

SOFTWARE:
Gallery 2.x
http://secunia.com/product/5879/

DESCRIPTION:
rgod has discovered a vulnerability in Gallery, which can be
exploited by malicious people to disclose sensitive information and
compromise a vulnerable system.

Input passed to the "stepOrder[]" parameter in "upgrade/index.php"
and "install/index.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 "magic_quotes_gpc" is disabled
and that "register_globals" is enabled.

This can further be exploited to include arbitrary PHP code injected
into "g2data/plugins_data/modules/watermark".

The vulnerability has been confirmed in version 2.0.3 and has also
been reported in prior versions. Other versions may also be affected.

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

Set "register_globals" to "Off".

PROVIDED AND/OR DISCOVERED BY:
