Netty is an asynchronous event-driven network application framework for
rapid development of maintainable high performance protocol servers and
clients.
Path to dependency file: /pom.xml
Path to vulnerable library: /home/wss-scanner/.m2/repository/io/netty/netty-handler/4.1.42.Final/netty-handler-4.1.42.Final.jar
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.
