Sun(sm) Alert Notification
      * Sun Alert ID: 102902
      * Synopsis: Security Vulnerability in the Authentication Mechanism
        for Solaris Management Console (SMC) May Lead to Escalation of
        Privileges
      * Category: Security
      * Product: Solaris 9 Operating System, Solaris 10 Operating System,
        Solaris 8 Operating System
      * BugIDs: 6365758
      * Avoidance: Patch, Workaround
      * State: Resolved
      * Date Released: 05-Jun-2007
      * Date Closed: 05-Jun-2007
      * Date Modified:

1. Impact

    A security vulnerability in the authentication mechanism for Solaris
    Management Console (SMC) may allow a local or remote authenticated
    user to gain unauthorized root access to a Solaris system.

    Sun acknowledges with thanks, Adam Gowdiak for bringing this issue to
    our attention.

2. Contributing Factors

    This issue can occur in the following releases:

    SPARC Platform
      * Solaris 8 without patch 111313-05
      * Solaris 9 without patch 112945-45
      * Solaris 10 without patch 121308-09

    x86 Platform
      * Solaris 8 without patch 111314-05
      * Solaris 9 without patch 114193-35
      * Solaris 10 without patch 121309-09

    Note: The described issue will only occur if the Solaris Management
    Console (SMC) is running on the system.

    To determine if SMC is running on a system, the following command can
    be run (as 'root' on Solaris 8 and 9 systems and as any user on
    Solaris 10 systems):

    for Solaris 8:
     # /etc/init.d/init.wbem status
     Solaris Management Console server not running on port 898

    for Solaris 9:
     # /etc/init.d/init.wbem status
     Solaris Management Console server version 2.1.0 running on port 898

    for Solaris 10:
     $ svcs svc:/application/management/wbem
     STATE      STIME    FMRI
     online     Apr_12   svc:/application/management/wbem:default

3. Symptoms

    There are no predictable symptoms that would indicate the described
    issue has been exploited to gain unauthorized root access on a system.

4. Relief/Workaround

    To prevent this issue from occurring until the resolution patches can
    be applied, the SMC server can be stopped by issuing the following
    command as 'root' (note that this will remove the functionality of the
    SMC service on that host):

    For Solaris 8 and 9:
     # /etc/init.d/init.wbem stop

    For Solaris 10:
     # svcadm disable svc:/application/management/wbem

5. Resolution

    This issue is addressed in the following releases:

    SPARC Platform
      * Solaris 8 with patch 111313-05 or later
      * Solaris 9 with patch 112945-45 or later
