Sun(sm) Alert Notification
      * Sun Alert ID: 102278
      * Synopsis: Security Vulnerability in the SunPlex Manager Software
        Delivered With Sun Cluster 3.1 4/04
      * Category: Security
      * Product: Sun Cluster 3.1
      * BugIDs: 5076947
      * Avoidance: Upgrade
      * State: Resolved
      * Date Released: 29-Mar-2006
      * Date Closed: 29-Mar-2006
      * Date Modified:

1. Impact

    A local user who has been granted the "solaris.cluster.gui"
    authorization may be able to view files which would normally be
    inaccessible to that user due to a security vulnerability in the Sun
    Cluster SunPlex Manager GUI.

2. Contributing Factors

    This issue can occur in the following releases:

    SPARC Platform
      * Sun Cluster 3.1 4/04 (for Solaris 8 and 9)

    x86 Platform
      * Sun Cluster 3.1 4/04 (for Solaris 9)

    Notes:
     1. Sun Cluster 3.1 4/04 is not supported on Solaris 10.
     2. Sun Cluster 3.1 versions later than 4/04 are not affected by this
        issue.
     3. Sun Cluster 3.0 and earlier are not affected by this issue.

    To determine if Sun Cluster 3.1 4/04 is installed on a system, the
    following command can be run:
     $ /usr/cluster/bin/scinstall -p | grep 3.1u2
     3.1u2

    If the system returns 3.1u2 (as in the example above), then it is
    impacted by this issue.

    To determine if a local user has been granted the
    "solaris.cluster.gui" the auths(1) command can be used, as in the
    following example:
     $ auths username
     solaris.system.date,solaris.cluster.gui

3. Symptoms

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

4. Relief/Workaround

    To work around the described issue, temporarily disable SunPlex
    Manager by running the script as shown below (as 'root'):
     # /etc/init.d/initspm stop

    Note: Disabling this service will mean that users will be unable to
    administer the Sun Cluster software using the SunPlex Manager
    Software.

5. Resolution

    This issue is addressed in the following releases:

    SPARC Platform
      * Sun Cluster 3.1 9/04 (for Solaris 8 and 9) or later

    x86 Platform
      * Sun Cluster 3.1 9/04 (for Solaris 9) or later

    Note: It is necessary to install or upgrade to Sun Cluster 3.1 9/04 or
    later.
