"IBM WebSphere Application Server 6.1 before Fix Pack 43 appears to be
running on the remote host.  As such, it is potentially affected by
the following vulnerabilities :

  - An unspecified error exists related to WS-Security
    enabled JAX-RPC applications. (PM45181)

  - Insecure file permissions are applied to the files in
    the '$WAS_HOME/systemapps/isclite.ear' and
    '$WAS_HOME/bin/client_ffdc' directories. These
    permissions can allow a local attacker read or write
    files in those directories. Note this issue only
    affects the application on the IBM i operating system.
    (PM49712)

  - An error exists in the class
    'javax.naming.directory.AttributeInUseException' and can
    allow old passwords to still provide access. This error
    is triggered when passwords are updated by using IBM
    Tivoli Directory Server. (PM52049)

  - Unspecified cross-site scripting issues exist related to
    the administrative console. (PM52274, PM53132)

  - SSL client certificate authentication can be bypassed
    when all of the following are true (PM52351) :

      - SSL is enabled with 'SSLEnable'
      - SSL client authentication is enabled with
        'SSLClientAuth required_reset'. This is not enabled
        by default. Also note, 'SSLClientAuth required' is
        not affected
      - SSLv2 has not been disabled with
        'SSLProtocolDisable SSLv2'
      - 'SSLClientAuthRequire' is not enabled

  - An issue related to the weak randomization of Java hash
    data structures can allow a remote attacker to cause a
    denial of service with maliciously crafted POST requests.
    (PM53930)"
