   Solution  238416 :   A Vulnerability in Access Manager 7.1 may Allow
   Unauthorized Access to Resources          
  
   Product
   Sun Java System Access Manager 7.1

   Date of Workaround Release: 11-Jun-2008

   Date of Resolved Release: 24-Dec-2008

   SA Document Body
   In AM 7.1 and later patches, a user can get to AM login screen,  ... 
   (see below for details):

   1. Impact

   Under certain configurations, a security vulnerability in Sun Java
   System Access Manager 7.1 may allow a remote unprivileged user to
   gain unauthorized access to resources or to gain administrator
   privileges without any authentication.

   2. Contributing Factors

   This issue can occur in the following releases:
     * Sun Java System Access Manager 7.1 without patch 140504-02

   SPARC Platform
     * Sun Java System Access Manager 7.1 without patch 126356-02

   x86 Platform
     * Sun Java System Access Manager 7.1 without patch 126357-02

   Linux Platform
     * Sun Java System Access Manager 7.1 without patch 126358-02

   Windows Platform
     * Sun Java System Access Manager 7.1 without patch 126359-02

   HP-UX Platform
     * Sun Java System Access Manager 7.1

   To determine the version of 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
       # <access-manager-install-dir>/bin/amadmin --version
       Sun Java System Access Manager 2005Q4
   Other versions of Sun Java System Access Manager are not affected.
   Note: Only Sun Java System Access Manager 7.1 installations that
   are configured to use Sun Directory Server Enterprise Edition
   (DSEE) 5.2 in any configuration or Sun Directory Server Enterprise
   Edition (DSEE) 6 with a non-default configuration mode (that allows
   binds without a password) as the backend are affected by this issue.

   3. Symptoms

   There are no predictable symptoms that would show that the described 
   vulnerability has been exploited to gain unauthenticated access to 
   resources.

   4. Workaround

   Currently there is no workaround for this issue if AM 7.1 is
   configured
   to use DSEE 5.2 as the LDAP repository.
   To workaround this issue for Access Manager configured to use DSEE 6, 
   DSEE 6 needs to be configured in the default DSEE 6 configuration which 
   is to "require a bind password". Access Manager login will display 
   "Authentication Failed." in this case thereby preventing this issue from 
   being exploited.

   This can be done by executing the 'dsconf' command on the DSEE 6 as
   follows:
     # ./dsconf set-server-prop -e require-bind-pwd-enabled:on
     Enter "cn=Directory Manager" password:
   To print the value of require-bind-pwd-enabled:
     # ./dsconf get-server-prop -e require-bind-pwd-enabled
     Enter "cn=Directory Manager" password:
     require-bind-pwd-enabled  :  on
   After you have set the "require-bind-pwd-enabled" option to "on," you
   will be not be able to login to Access Manager with a blank password.

   5. Resolution

   This issue is addressed in the following releases:
     * Sun Java System Access Manager 7.1 with patch 140504-02

   SPARC Platform
     * Sun Java System Access Manager 7.1 with patch 126356-02

   x86 Platform
     * Sun Java System Access Manager 7.1 with patch 126357-02

   Linux Platform
     * Sun Java System Access Manager 7.1 with patch 126358-02

   Windows Platform
     * Sun Java System Access Manager 7.1 with patch 126359-02
