JBoss Security Update for Bedework 3.7
As you may be already aware from messages on the Bedworkwork Bedwork lists and/or the JBoss list, a vlunerability vulnerability has been identified with respect to the JBoss JMX console. Although this vulnerability is in JBoss, not Bedework itself, Bedework installations may be affected.
The Bedework 3.7 quickstart has been modified to make the JMX console more secure, as will all . All future Bedework releases will inherit these changes.
Simply performing a subversion update to your existing installation will not address the vulnerability. You will To secure your JBoss installation, you need to to "manually" follow the procedure described below:
1. Locate the <security-constrain> constraint> element (around line 101) in the file
jboss-5.1.0.GA/server/default/deploy/jmx-console.war/WEB-INF/web.xml
<security-constraint>
<web-resource-collection>
<web-resource-name>HtmlAdaptor</web-resource-name>
<description>An example security config that only allows users with the
role JBossAdmin to access the HTML JMX console web application
</description>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>JBossAdmin</role-name>
</auth-constraint>
</security-constraint>
...
To determine if your JBoss instance has been compromised, look in directory
jboss-5.1.0.GA/server/default/deploy/management/
If you see the directory
iesvc.war
then your instance has been infected.

3. Lastly, change the JMX console password. In the Bedework quickstart configuration the userid and password are found in the file
jboss-5.1.0.GA/server/default/conf/props/jmx-console-users.properties
If you followed the instructions to secure Bedework during your initial installation (see https://wiki.jasig.org/display/BWK37/BW+3.7+Securing+Bedework ), you may have already changed the JMX console password.
4. Note that it is not good practice to run any web service as a privileged user (e.g. "root"). Therefore, to minimizie your risk overall, you should run JBoss JBoss under an an unprivileged account.
