OVERVIEW

        A cross-site tracing vulnerability has been found in Novell ZENworks
        Configuration Management (ZCM).


IMPACT

        According to OWASP, a cross-site tracing attack has the following
        impact:
        
        "The client sends an HTTP TRACE with all header information including
        cookies, and the server simply responds with that same data." [1]
        
        This essentially means that an attacker could potentially pilfer
        credentials and other sensitive information.
        
        The National Vulnerability Database has the following additional
        information:
        
        "The xplat agent in Novell ZENworks Configuration Management (ZCM)
        10.3.x before 10.3.4 and 11.x before 11.2 enables the HTTP TRACE
        method, which might make it easier for remote attackers to conduct
        cross-site tracing (XST) attacks via unspecified vectors." [2]


MITIGATION

        The vulnerability is fixed in ZCM 10.3.4. There is currently no fix
        for ZCM 11.1. Novell states on their website that it has been
        "Reported to Engineering".[3]
