SA Document Body

A Security Vulnerability in Sun Java System Access Manager May Allow 
Privilege Escalation of Sub-Realm Administrators


1. Impact

A security vulnerability in Sun Java System Access Manager may allow a 
sub-realm administrator to escalate their privileges and access the root 
realm as an administrator.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform:

    * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10) without 
      patch 126356-02

x86 Platform:

    * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10) without 
      patch 126357-02

Linux:

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

Windows:

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

Other:

    * Sun Java System Access Manager 7.1 WAR file-based installation (all 
      platforms) without patch 140504-02

Note: Sun Java System Access Manager 7.0 and earlier are not impacted by 
this issue.

To determine if Sun Java System Access Manager is installed, the following 
command can be run on a Solaris system:

% pkginfo -l SUNWamsvc || echo "Sun Java Access Manager not installed"
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 the Sun 
Java System Access Manager).

3. Symptoms

There are no predictable symptoms that would indicate this issue has been 
exploited.

4. Workaround

There is no workaround for this issue. Please see the Resolution section 
below.

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 126356-02 or later

x86 Platform:

    * Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10) with 
      patch 126357-02 or later

Linux:

    * Sun Java System Access Manager 7.1 with patch 126358-02 or later

Windows:

    * Sun Java System Access Manager 7.1 with patch 126359-02 or later

Other:

    * Sun Java System Access Manager 7.1 WAR file-based installation (all 
      platforms) with patch 140504-02 or later


Note: After applying the recommended or latest patch, the "amadmin" user 
will only be able to login to the admin console through either the 
"DataStore" or the "Application" modules.

On systems running Access Manager 7.1 in legacy mode the following commands 
should be run to ensure creation of the Data Store Authentication module 
instance:

$ ldapmodify -D "cn=Directory Manager" -w <password> -h <host> -p <port> << EOF
dn: $rootdn
changetype: modify
add: sunRegisteredServiceName
sunRegisteredServiceName: sunAMAuthDataStoreService
EOF

$ ldapmodify -D "cn=Directory Manager" -w <password> -h <host> -p <port> << EOF
dn: ou=default,ou=OrganizationConfig,ou=1.0,ou=sunAMAuthDataStoreService,ou=services,$rootdn
changetype: modify
add: sunkeyvalue
sunkeyvalue: sunAMAuthDataStoreAuthLevel=0
EOF
