"IBM WebSphere Application Server 7.0 before Fix Pack 21 appears to be
running on the remote host.  As such, it is potentially affected by
the following vulnerabilities :

  - An unspecified cross-site scripting issue exists
    related to the 'Web 2.0 Messaging service'. (PM37840)

  - A security exposure when using WS-Security could result
    in a user gaining elevated privileges in applications
    using JAX-WS. (PM43585 / CVE-2011-1377)

  - 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 to 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)"
