CVE-2010-0684: Apache ActiveMQ Persistent Cross-Site Scripting (XSS)
Vulnerability
==============================================================

Security Advisory 03.30.2010

I. BACKGROUND

Apache ActiveMQ  is the most popular and powerful open source
messaging and Integration Patterns provider.

http://activemq.apache.org/

II. DESCRIPTION

Remote unauthenticated exploitation of an input validation
vulnerability in Apache Software Foundation's ActiveMQ server could
allow an attacker to perform a
stored or persistent cross-site scripting (XSS) attack.  The code
responsible for parsing HTTP requests is vulnerable to an XSS
vulnerability. When parsing the JMSDestination parameter from a GET
request to /createDestination.action page, the value of this variable
is directly inserted into the HTML code that can be accessed by using
URLs such as /queues.jsp. This allows an attacker to run arbitrary
JavaScript in the context of the affected domain of the ActiveMQ
administration console.

III. ANALYSIS

Successful exploitation of this vulnerability allows an attacker to
conduct an XSS attack on a user. This could allow an attacker to steal
cookies, inject content into pages, or submit requests using the
user's credentials.  To exploit this vulnerability, an attacker must
send malicious request to the vulnerable Active MQ server such as the
following request:
http://www.example.com/createDestination.action?JMSDestination=[XSS_PAYLOAD]
Once this request is sent, anyone accessing the ActiveMQ queues would
have the XSS payload executed in the context of the browser session
being used to browse using a URL such as:
http://www.example.com/queues.jsp
