Vulnerability Details

An issue was found in all versions of io.netty:netty-all. Host verification in Netty is disabled by default. This can lead to MITM attack in which an attacker can forge valid SSL/TLS certificates for a different hostname in order to intercept traffic that doesn’t intend for him. This is an issue because the certificate is not matched with the host.
