CVE-2011-4085: Medium severity jboss enterprise application platform vulnerability
By using a specially crafted HTTP request, the first layer of authentication for the invoker servlets deployed by httpha-invoker can be bypassed, as the access restrictions only apply for GET and POST. Due to the second layer of authentication provided by the security interceptor, there is no way to directly exploit this flaw. If a user misconfigured the security interceptor or inadvertently disabled it, this flaw would be exploitable.
The fix is to remove the verb-specific <http-method> elements from web.xml. This issue is a regression of CVE-2010-0738.
Other sources
The servlets invoked by httpha-invoker in JBoss Enterprise Application Platform before 5.1.2, SOA Platform before 5.2.0, BRMS Platform before 5.3.0, and Portal Platform before 4.3 CP07 perform access control only for the GET and POST methods, which allow remote attackers to bypass authentication by sending a request with a different method. NOTE: this vulnerability exists because of a CVE-2010-0738 regression.
