Summary
It is possible to configure Apache CXF to use the com.sun.net.ssl implementation via 'System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");'. When this system property is set, CXF uses some reflection to try to make the HostnameVerifier work with the old com.sun.net.ssl.HostnameVerifier interface. However, the default HostnameVerifier implementation in CXF does not implement the method in this interface, and an exception is thrown. However, in Apache CXF prior to 3.2.5 and 3.1.16 the exception is caught in the reflection code and not properly propagated. What this means is that if you are using the com.sun.net.ssl stack with CXF, an error with TLS hostname verification will not be thrown, leaving a CXF client subject to man-in-the-middle attacks.

Cuando se establece esta propiedad de sistema, CXF utiliza determinada reflexi\u00f3n para intentar hacer que HostnameVerifier funcione con la antigua interfaz com.sun.net.ssl.HostnameVerifier. Sin embargo, la implementaci\u00f3n predeterminada de HostnameVerifier en CXF no implementa el m\u00e9todo en esta interfaz y se lanza una excepci\u00f3n. Sin embargo, en Apache CXF en versiones anteriores a la 3.2.5 y 3.1.16, la excepci\u00f3n queda atrapada en el c\u00f3digo de reflexi\u00f3n y no se propaga correctamente. Esto significa que, si est\u00e1 utilizando la pila com.sun.net.ssl con CXF, no se producir\u00e1 un error con la verificaci\u00f3n del nombre de host TLS, lo que dejar\u00e1 a un cliente CXF sujeto a ataques Man-in-the-Middle (MitM)."
