Netty is an asynchronous event-driven network application framework for
rapid development of maintainable high performance protocol servers and
clients.
Path to dependency file: /chaincode/simple/java/build.gradle
Path to vulnerable library: /home/wss-scanner/.gradle/caches/modules-2/files-2.1/io.netty/netty-handler/4.1.38.Final/ebf1f2bd0dad5e16aa1fc48d32e5dbe507b38d53/netty-handler-4.1.38.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.
