XSS vulnerability in Drupal's MP3 Player contributed module (version
Discovered by Martin Barbella <martybarbella () gmail com>
Description of Vulnerability:
Drupal is a free software package that allows an individual or a
community of users to easily publish, manage and organize a wide
variety of content on a website. (From: http://drupal.org/about)
The MP3 Player module allows users to use the WordPress Audio Player in Drupal.
to create the audio player is generated, resulting in a cross site
The module also fails to sanitize various inputs on the MP3 player
administration page. In the cases where the user is prompted for 6
digit hex values to use as colors for the player, it will only check
that the value is 6 characters long, and will not verify that it is
hexadecimal, but as this is both difficult to exploit, and requires
that the user can administer the MP3 player module, the rest of this
report will only focus on the previous vulnerability.
This has been confirmed in MP3 Player 6.x-1.0-beta1. Other versions
may also be affected.
Stored attacks are those where the injected code is permanently stored
on the target servers, such as in a database, in a message forum,
visitor log, comment field, etc. The victim then retrieves the
malicious script from the server when it requests the stored
information. (From OWASP:
A user must have permission to create nodes of a type that use the audio player.
Proof of concept:
1. Install the MP3 Player module and its dependencies.
2. Create a new content type with a file field that accepts mp3s.
3. Make sure that MP3 Player will be used with the field that you have created.
4. Create a file named "+alert(document.cookie)+".mp3
5. Create a node with the new content type, and upload this file.
6. Note that an alert box will be displayed when viewing this node.
