Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.2 before 4.2.0.CP09 and 4.3 before 4.3.0.CP08 allows remote attackers to obtain sensitive information about "deployed web contexts" via a request to the status servlet, as demonstrated by a full=true query string. NOTE: this issue exists because of a CVE-2008-3273 regression.

By using a specially crafted HTTP request, the authentication of the jmx-console can be bypassed, as the access restrictions only apply for GET and POST.

Current setting is:

<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>

and should be changed to block ALL http-methods.
