Internal IP Address Leak - JBoss Application Server
---------------------------------------------------

                 Key: JBAS-5507
                 URL: http://jira.jboss.com/jira/browse/JBAS-5507
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: Tested on Windows / Linux JBoss installations (4.0.3, 4.0.4, 4.2.2)
            Reporter: Jeremy Carroll

When sending an HTTP 1.0 request that results in a 302 redirect, JBoss will leak the internal IP address of the server in the Location response. Basically you create a HTTP 1.0 request to a URL which will result in a 302. Then you can see in the internal server IP / name. I have mitigated this issue with a front end Web Application Firewall by denying HTTP 1.0 requests as a workaround. Is there a setting in tomcat or JBoss to not allow this to happen? It is pretty widespread from testing I have done in the lab. It results in a PCI compliance violation by scoring it as an exploit.

Example:

GET /application HTTP/1.0

HTTP/1.1 302 Moved Temporarily
Server: Apache-Coyote/1.1
Location: http://arcenae:8090/application/
