Other sources

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.

The undertow client is not checking the server identity presented by the server certificate in https connections. This should be performed by default in https and in http/2.

Undertow could provide weaker than expected security, caused by not checking the server identity the server certificate presents in HTTPS connections. An attacker could exploit this vulnerability to launch further attacks on the system
