DOCUMENT ID: 51340
SYNOPSIS: Security vulnerability in Sun Cluster 2.2
DETAIL DESCRIPTION:


    Sun(sm) Alert Notification

    * Sun Alert ID: 51340
    

      *Synopsis: Security Vulnerability in Sun Cluster 2.2
    

      *Category: Security
    

      *Product: Sun Cluster
    * BugIDs: 4805121, 4318821
    * Avoidance: Patch
    

      *State: Resolved
    * Date Released: 20-May-2003, 20-Jun-2003
    * Date Closed: 20-May-2003
    * Date Modified: 20-Jun-2003


    1. Impact

Database user names and passwords may be readable for local unprivileged
users because they are held in a plain text cluster configuration file.


    2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

    * Sun Cluster 2.2 (for Solaris 2.6) without patch 109208-13
    * Sun Cluster 2.2 (for Solaris 7) without patch 109209-12
    * Sun Cluster 2.2 (for Solaris 8) without patch 109210-11

Note that due to a patch removal script issue, the vulnerability will
recur if one of the following patches are removed from the system and
the fix is not re-installed:

    * Sun Cluster 2.2 removal of patch 109208-14 through 109208-17
    * Sun Cluster 2.2 removal of patch 109209-13 through 109209-16
    * Sun Cluster 2.2 removal of patch 109210-12 through 109210-15

This removal script issue is resolved by Bug 4805121 addressed in the
patches listed in the Resolution section below.

Only systems that have the HA-Oracle or HA-Sybase DBMS services
registered with the cluster framework are affected by this issue. The
issue is *not* with the Oracle or Sybase software.

Note: Sun Cluster 3.x is not impacted by this issue.


    3. Symptoms

There are no reliable symptoms that would show the described issue has
occurred.


SOLUTION SUMMARY:


    4. Relief/Workaround

There is no workaround. Please see the "Resolution" section below.

It is not possible to simply change the permissions of the cluster
configuration file since there are a number of processes that modify
this file and at the same time set the permissions of the file to the
default values.


    5. Resolution

This issue is addressed in the following releases:

SPARC Platform

    * Sun Cluster 2.2 (Solaris 2.6) with patch 109208-18 or later
    * Sun Cluster 2.2 (Solaris 7) with patch 109209-17 or later
    * Sun Cluster 2.2 (Solaris 8) with patch 109210-16 or later

Note: With the above patches installed, the cluster configuration file
is accessible by the superuser only.


    Change History

20-Jun-2003:

    * Updated Contributing Factors regarding "patch removal script" issue
