Security issue in jboss client netty-handler

Solution Unverified - Updated -


Analysing security issues of jboss-client, I came across an issue reported by Sonatype: sonatype-2020-0026 (wildfly-client-all:19.1.0.FINAL) which described the issue as

The netty-handler package is vulnerable to Improper Certificate Validation. The newHandler methods in SslContext.class do not verify hostnames by default when generating a new SSLEngine. An attacker can exploit this as part of a Man-in-the-Middle (MITM) attack to spoof their identity and gain access to or modify sensitive data._
