26 May 2010
AusCERT Security Bulletin Summary
Product: Heartbeat (Drupal third-party module)
Operating System: UNIX variants (UNIX, Linux, OSX)
Impact/Access: Administrator Compromise -- Existing Account
Cross-site Scripting -- Existing Account
CVE Names: CVE-2010-2048
- --------------------------BEGIN INCLUDED TEXT--------------------
* Advisory ID: DRUPAL-SA-CONTRIB-2010-051
* Project: Heartbeat (third-party module)
* Version: 6.x
* Date: 2010-May-19
* Security risk: Critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
The Heartbeat project contains a suite of modules to display user activity
on a website. These modules do not properly sanitize some of their output,
allowing certain users the ability to insert arbitrary HTML and script code.
Such a cross site scripting (XSS) attack may lead to a malicious user
gaining full administrative access. Depending on how the modules are
configured, this vulnerability may extend to relatively unprivileged
users, such as those with the ability to post comments, user "shouts"
or other content.
* Heartbeat for Drupal 6.x versions prior to 6.x-4.9
Drupal core is not affected. If you do not use the contributed Heartbeat
modules, there is nothing you need to do.
Install the latest version:
* If you use the Heartbeat module for Drupal 6.x, update to
See also the Heartbeat project page.
Some aspects of the vulnerability were reported by Sebastian

Jochen Stals (Stalski), the module maintainer, and David Rothstein of
the Drupal Security Team
