Sun(sm) Alert Notification
      * Sun Alert ID: 102016
      * Synopsis: The Solaris Management Console (SMC) Enables TRACE HTTP
        by Default.
      * Category: Security
      * Product: Solaris 9 Operating System, Solaris 10 Operating System,
        Solaris 8 Operating System
      * BugIDs: 5090761
      * Avoidance: Patch, Workaround
      * State: Workaround
      * Date Released: 26-Oct-2005
      * Date Closed:
      * Date Modified:

1. Impact

    The Solaris Management Console (smc(1M)) is a graphical user interface
    that provides access to Solaris system administration tools which
    includes a web server that runs on port 898. This SMC web server
    enables the HTTP TRACE method by default which may allow a local or
    remote unprivileged user the ability to access sensitive information,
    such as cookies or authentication data, contained in the HTTP headers
    of an HTTP TRACE request.

    This issue is described in the CERT Vulnerability VU#867593 (see
    http://www.kb.cert.org/vuls/id/867593).

    Note: The HTTP TRACE method asks a web server to echo the contents of
    the request back to the client for debugging purposes. The HTTP TRACE
    method is described in the HTTP 1.1 standard (RFC 2616, section 9.8).
    The TRACE method is enabled by default in Solaris Management Console
    (SMC) webserver.

2. Contributing Factors

    This issue can occur in the following releases:

    SPARC Platform
      * Solaris 8
      * Solaris 9 without patch 116807-02
      * Solaris 10

    x86 Platform
      * Solaris 8
      * Solaris 9 without patch 116808-02
      * Solaris 10

    The described issue only occurs if the Solaris Management Console
    (smc(1M)) is running on the system.

    This can be determined by running the following command as the "root"
    user:
     # /etc/init.d/init.wbem status
     Solaris Management Console server not running on port 898

     # /etc/init.d/init.wbem status
     Solaris Management Console server version 2.1.0 running on port 898

3. Symptoms

    There are no predictable symptoms that would indicate the described
    issue has occurred.

4. Relief/Workaround

    The Trace method cannot be turned off. To workaround this issue until
    patches can be applied, sites may disable the Solaris Management
    Console (smc(1M)) by running the following command as the root user:

    To stop the running of the smc(1M) server:
     # /etc/init.d/init.wbem stop

    To prevent the smc(1M) server from starting upon successive reboots:
     # mv /etc/rc2.d/S90wbem /etc/rc2.d/disabled-S90wbem


5. Resolution

    This issue is addressed in the following releases:

    SPARC Platform
      * Solaris 9 with patch 116807-02 or later

    x86 Platform
      * Solaris 9 with patch 116808-02 or later

    A final resolution is pending completion.
