The remote web application server is affected by a vulnerability.


The version of IBM WebSphere Application Server Liberty running on the remote host is affected by a vulnerability as referenced in the 6602039 advisory.

- In the Eclipse Paho Java client library version 1.2.0, when connecting to an MQTT server using TLS and setting a host name verifier, the result of that verification is not checked. This could allow one MQTT server to impersonate another and provide the client library with incorrect information. (CVE-2019-11777)
