"According to its self-reported version, the IBM WebSphere MQ server
installed on the remote Windows host is 9.0.1 or 9.0.2 prior to 9.0.3.
It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists due to
    the insecure transmission of credentials in cleartext. A
    man-in-the-middle attacker can exploit this to disclose
    password information. Note that the software is only
    affected when PASSWORDPROTECTION=ALWAYS is set in
    mqclient.ini. (CVE-2017-1337)

  - An information disclosure vulnerability exists in
    WebSphere Application server traces when establishing
    CLIENT transport mode connections. A local attacker can
    exploit this to disclose sensitive information including
    passwords. (CVE-2017-1284)

  - A denial of service vulnerability exists due to improper
    handling of invalid messages. An authenticated, remote
    attacker can exploit this to cause an SDR or CLUSSDR
    channel to stop processing messages.");
