Descriptions

The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.

A flaw was found in undertow. The undertow client is not checking the server identity the server certificate presents in HTTPS connections. This is a compulsory step ( that should at least be performed by default) in HTTPS and in http/2.
