GLSA-200402-04 : Gallery 1.4.1 and below remote exploit vulnerability

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200402-04
(Gallery 1.4.1 and below remote exploit vulnerability)

Starting in the 1.3.1 release, Gallery includes code to simulate the behaviour
of the PHP 'register_globals' variable in environments where that setting
is disabled. It is simulated by extracting the values of the various
$HTTP_ global variables into the global namespace.

Impact :

A crafted URL such as
http://example.com/gallery/init.php?HTTP_POST_VARS=xxx causes the
'register_globals' simulation code to overwrite the $HTTP_POST_VARS which,
when it is extracted, will deliver the given payload. If the
payload compromises $GALLERY_BASEDIR then the malicious user can perform a
PHP injection exploit and gain remote access to the webserver with PHP
user UID access rights.

Workaround :

The workaround for the vulnerability is to replace init.php and
setup/init.php with the files in the following ZIP file:
http://prdownloads.sourceforge.net/gallery/patch_1.4.1-to-1.4.1-pl1.zip?download
