WS-2020-0408 (High) detected in netty-all-4.0.56.Final.jar #135
Netty is an asynchronous event-driven network application framework for
rapid development of maintainable high performance protocol servers and
clients.
Path to vulnerable library: /sdk/spring/azure-spring-data-gremlin/package/apache-tinkerpop-gremlin-server-minimal-3.3.4.tar/apache-tinkerpop-gremlin-server-minimal-3.3.4/lib/netty-all-4.0.56.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.
