                             [Win][UNIX/Linux]
 Inappropiate access to JBoss application server management functionality
                             21 February 2007
- ---------------------------------------------------------------------------

        AusCERT Advisory Summary
        ------------------------

Product:              JBoss Application Server
Operating System:     UNIX variants (UNIX, Linux, OSX)
                      Windows
Impact:               Inappropriate Access
Access:               Remote/Unauthenticated
Member content until: Wednesday, March 21 2007

OVERVIEW:
        
        A vulnerability in the JBoss application server has been publicly 
        disclosed. Successful exploitation of this vulnerability may result
        in unauthenticated access to administrative functions of the JBoss 
        server.


IMPACT: 

        By default, the JBoss server does not limit access to the JMX 
        Console and Web Console. By visiting a particular URL an attacker 
        may be able to access information about and functions control the 
        JBoss Server[1], without authentication. Information about this 
        vulnerability, including Google search strings designed to enumerate 
        vulnerable sites has been posted to a public mailing list[2].


MITIGATION:

        AusCERT recommends sites running JBoss ensure that access to the JMX 
        Console and Web Console is limited. Information on doing this can be 
        found in the JBoss website[3].
