Sun(sm) Alert Notification
     * Sun Alert ID: 101918
     * Synopsis: Security Vulnerability in the Logging Output of Sun Java
       System Access Manager
     * Category: Security
     * Product: Sun Java System Access Manager 2004Q2, Sun Java System
       Access Manager 6 2005Q1, Sun Java System Identity Server 6.1
     * BugIDs: 6269826
     * Avoidance: Patch, Workaround
     * State: Workaround
     * Date Released: 10-Jul-2007
     * Date Closed: 
     * Date Modified: 

1. Impact

   When the debug level within Sun Java System Access Manager (formerly
   Sun Java System Identity Server) is set to "message," login passwords
   may be logged in plain text and are therefore readable by local
   unprivileged users. This would allow that user to gain unauthorized
   access to user identities which are managed by Sun Java System Access
   Manager.

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * Sun One Identity Server 6.1 for Solaris 8 and 9 without patch
       117586-16
     * Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
       without patch 115766-09
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 9 without
       patches 119465-02 and 119466-02
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 10 without
       patch 119465-09

   x86 Platform
     * Sun One Identity Server 6.1 for Solaris 8 and 9
     * Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
       without patch 120091-09
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 9 without
       patches 119465-02 and 119467-02
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 10 without
       patch 119467-09

   Linux
     * Sun Java System Acess Manager 6.2 (2004Q2) without patch
       119409-09
     * Sun Java System Access Manager 6 (2005Q1) for RHEL2.1 without
       patch 119502-02

   Note: Patch 119465-02 is a "generic" patch, applicable to both
   SPARC and x86 platforms.

   Systems are only impacted when the "com.iplanet.services.debug.level"
   property is set to "message" in the
   "/etc/opt/SUNWam/config/AMConfig.properties" file (this flag is
   usually set to help with debugging).

   The debug level can be determined by looking at the
   "AMConfig.properties" file for an entry similar to the following
   (example):
    com.iplanet.services.debug.level=message

   To determine the version of Sun Java System Access Manager on a
   system, the following command can be run:
    $ /opt/SUNWam/bin/amadmin -n

   or for Identity server:
    $ /opt/SUNWam/bin/amserver -n
    Sun Java System Identity Server version 2004Q2

3. Symptoms

   Plain text passwords are shown in the "/var/opt/SUNWam/debug/amAuth"
   debug file. The following is a sample output of the "amAuth" debug
   file after login, where "Login.Token2=testpassword" appears in plain
   text:
    # grep -i token2 amAuth | more
    LoginStateReturning.. hash :{channelName=Login, module=Membership, Login.To
ken2=
    password, Login=Login, Login.Token1=user1}
    LoginStateReturning.. hash :{channelName=Login, module=Membership, Login.To
ken2=
    testpassword, Login=Login, Login.Token1=testuser}
    LoginStateReturning.. hash :{channelName=Login, module=Membership, Login.To
ken2=
    testpassword, Login=Login, Login.Token1=testuser} 

4. Relief/Workaround

   To work around the described issue, do not use the "message" debug
   mode. Instead, set the debug level in the
   "/etc/opt/SUNWam/config/AMConfig.properties" file to "error", as in
   the following example:
    com.iplanet.services.debug.level=error

5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform
     * Sun One Identity Server 6.1 (for Solaris 8 and 9) with patch
       117586-16 or later
     * Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
       with patch 115766-09 or later
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 9 with
       patches 119465-02 or later and 119466-02 or later
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 10 with
       patch 119465-09 or later

   x86 Platform
     * Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
       with patch 120091-09 or later
     * Sun Java System Access Manager 6 (2005Q1) for Solaris 9 with
       patches 119465-02 or later and 119467-02 or later
     * Sun Java System Access Manager 6 2005Q1) for Solaris 10 with patch
       119467-09 or later

   Linux
     * Sun Java System Acess Manager 6.2 (2004Q2) with patch
       119409-09 or later
     * Sun Java System Access Manager 6 2005Q1 (for RHEL2.1) with patch
       119502-02 or later

   Notes:
    1. Both patches listed for Sun Java System Access Manager 6 (2005Q1)
       for Solaris 9 on the SPARC and x86 platforms must be installed to
       resolve this issue.
    2. Patch 119465-02 is a "generic" patch, applicable to both SPARC
       and x86 platforms.
    3. Sun One Identity Server 6.1 for Solaris 8 and 9 on x86 requires an
       upgrade to Sun Java System Access Manager 6.2 to resolve this
       issue.

   A final resolution is pending completion.
