Upgrade org.apache.cxf:cxf-rt-transports-http to version 3.1.16, 3.2.6 or higher.
Overview
org.apache.cxf:cxf-rt-transports-http is an open source services framework.
Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). When configuring CXF to use the com.sun.net.ssl implementation via:
System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
It attempts to make the HostnameVerifier work with the old com.sun.net.ssl.HostnameVerifier interface, but the default HostnameVerifier implementation in CXF does not implement the method in this interface which caused an exception is thrown. This exception caught in the reflection code and not properly propagated. Thus the TLS hostname verification error will not be thrown, leaving a CXF client subject to man-in-the-middle attacks.
