DESCRIPTION:
A security issue and a vulnerability have been reported in the
Embedded Field module for Drupal, which can be exploited by malicious
users to conduct script insertion attacks and to compromise a
vulnerable system.

1) Input passed via the audio or video path is not properly sanitised
before being used. This can be exploited to insert arbitrary HTML and
script code, which will be executed in a user's browser session in
context of an affected site when the malicious data is being viewed.

Successful exploitation of this vulnerability requires that the site
has a content type with an embedded media field allowing users to
upload custom thumbnails and the user has access to create or edit
the content type.

2) The security issue is caused due to improper validation of
uploaded files' extensions. This can be exploited to execute
arbitrary PHP code by uploading a PHP file with e.g. a ".phtml" file
extension.

Successful exploitation of this vulnerability requires that the site
has a content type with an embedded media field that has the custom
audio or video provider file enabled, and that the user has access to
create or edit the content type.

The vulnerabilities are reported in versions prior to 5.x-1.12,
6.x-1.26, and 6.x-2.4.

SOLUTION:
Update to version 5.x-1.12 or later, 6.x-1.26 or later, or 6.x-2.4 or
later.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Justin Klein Keane.
