OVERVIEW

        A vulnerability has been identified in IBM Websphere Application 
        Server 6.1 and 7.0, which could be exploited to bypass security 
        restrictions.


IMPACT

        A WS-Security policy set at operation level does not properly handle 
        inbound requests that lack a SOAPAction or WS-Addressing Action. 
        
        A remote attack could bypass security restrictions due to this flaw 
        in JAX-WS applications [1, 2].


MITIGATION

        The vendor recommends applying the latest Fix Pack for IBM Websphere 
        Application Server [3].
