Sun(sm) Alert Notification
     * Sun Alert ID: 103069
     * Synopsis: Installation of Sun Java System Access Manager 7.1 on
       Sun Java System Application Server 9.1 or 8.x May Compromise
       Application Server Security
     * Category: Security
     * Product: Sun Java System Access Manager 7.1
     * BugIDs: 6571897
     * Avoidance: Patch, Workaround
     * State: Workaround
     * Date Released: 27-Sep-2007
     * Date Closed: 
     * Date Modified: 14-Jan-2008, 17-Jan-2008

1. Impact

   There are two vulnerabilities associated with this issue:

   1. When Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 9.1 container and the container is
   restarted, no authentication screen is displayed. Any application
   using container based authentication would no longer work correctly as
   any users would be granted access without authentication. This can
   lead to unprivileged non-administrative users performing
   administrative tasks. As an example, the Admin Console application
   (which is a pre-deployed system application on the Application Server
   used to Administer the Application Server) no longer prompts users for
   authentication when accessing this application. Thus anyone, whether
   they have administrative privileges or no privileges, could administer
   the Application Server.

   2. When Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 8.x container, the installation may be
   vulnerable to malicious code. If an application is deployed in such an
   environment, then a local or remote unprivileged user may be able to
   execute arbitrary code with the privileges of the deployed
   application.

2. Contributing Factors

   These issues can occur in the following releases:

   SPARC Platform
     * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10)
       without patch 126356-01

   x86 Platform
     * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10)
       without patch 126357-01

   Linux
     * Sun Java System Access Manager 7.1 without patch 126358-01

   Windows
     * Sun Java System Access Manager 7.1 without patch 126359-01

   HP-UX
     * Sun Java System Access Manager 7.1

   Note: No other versions of Sun Java System Access Manager or Sun Java
   System Application Server, or Access Manager 7.1 on any other Web
   container are affected by this issue.

   These vulnerabilities may be present under any one of the following
   conditions:

   a) If Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 9.1 container

   b) If Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 8.x container

   c) If Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 8.x container, and then the system is
   upgraded to Sun Java System Application Server 9.1

   d) If you performed the Sun Java System Application Server 8.x-> 9.1
   upgrade between the installation of Sun Java System Access Manager 7.1
   and application of Sun Java System Access Manager patch 7.1P1 (where
   this issue is fixed), then you are impacted.

   To determine the version of Sun Java System Access Manager on a
   Solaris system, the following command can be run:
    % pkginfo -l SUNWamsvc
     PKGINST:  SUNWamsvc
        NAME:  Sun Java System Access Manager Services
    CATEGORY:  application
        ARCH:  all
     VERSION:  7.1,REV=06.12.19.15.12

   To determine the version of Sun Java System Access Manager on other
   systems, the following command can be run:
    # <access-manager-install-dir>/bin/amadmin --version
    Sun Java System Access Manager 7.1

   (Where <access-manager-install-dir> is the installation directory of
   Sun Java System Access Manager).

3. Symptoms

   1. If Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 9.1 container, the container is restarted,
   and no authentication screen is displayed, this vulnerability is
   present.

   2. If Sun Java System Access Manager 7.1 is installed in a Sun Java
   System Application Server 8.x container, and the following 2 lines are
   present in the
   "<install-dir>/SUNWappserver/appserver/domains/domain1/config/server.p
   olicy" file:
    permission java.security.AllPermission "MonitoringAuth.*";
    permission java.security.AllPermission "MonitoringPolicy.*";

   then this vulnerability is present. 

4. Relief/Workaround

   To work around the described issues, apply the following to the
   server.policy file located in the
   "<install-dir>/SUNWappserver/appserver/domains/domain1/config/server.p
   olicy" directory:

   1. Remove the following lines:
    permission java.security.AllPermission "MonitoringAuth.*";
    permission java.security.AllPermission "MonitoringPolicy.*";

   2. Add the following lines:
    permission javax.management.MBeanServerPermission "*";
    permission javax.management.MBeanPermission "*", "*";
    permission javax.management.MBeanTrustPermission "*";

   3. Add the following lines:
    permission java.io.FilePermission
    "$MFWK_BASEDIR_CONF/var/opt/$MFWK_PROD_DIR/logs/*", "delete,write";

   (where $MFWK_BASEDIR_CONF is "/" when the default package installation
   directory is "/opt" (solaris), or "/opt/sun" (Linux, HP-UX).

   for Windows:
    permission java.io.FilePermission
    "$JES5_install_dir<>\share\mfwk\logs\*", "delete,write";

   (where $JES5_install_dir is the JES 5 installation directory on
   Windows platform)

   4. Stop and restart the Application Server container

5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform
     * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10) with
       patch 126356-01 or later

   x86 Platform
     * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10) with
       patch 126357-01 or later

   Linux
     * Sun Java System Access Manager 7.1 with patch 126358-01 or
       later

   Windows
     * Sun Java System Access Manager 7.1 with patch 126359-01 or
       later

   A final resolution is pending completion.
