"The IBM WebSphere Application Server running on the remote host is
version 6.1.0.47 / 7.0.0.37 / 8.0.0.10 / 8.5.5.5 or prior. It is,
therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in the
    SNMP component due to improper handling of configuration
    data. An authenticated, remote attacker can exploit this
    disclose sensitive information. (CVE-2015-0174)

  - An unspecified flaw exists in the liberty profile due to
    improper handling of authData elements. An
    authenticated, remote attacker can exploit this to gain
    elevated privileges. (CVE-2015-0175)

  - An unspecified flaw exists in the liberty profile that
    is triggered when the run-as user for EJB is not honored
    under multi-threaded race conditions. An authenticated,
    remote attacker can exploit this to gain elevated
    privileges. (CVE-2015-1882)

  - A flaw exists that allows a remote attacker to execute
    arbitrary code by connecting to a management port using
    a specific sequence of instructions. (CVE-2015-1920)");
