QID 995503: Java (Maven) Security Update for io.netty:netty-handler (GHSA-57m8-f3v5-hm5m)

Netty-handler has been found to no validate hostnames when using TLS in its default configuration. As a result netty-handler is vulnerable to man-in-the-middle attacks. Users would need to set the protocol to "HTTPS" in the SSLParameters of the SSLEngine to opt in to host name validation. A change in default behavior is expected in the 5.x release branch with no backport planned.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.

  • CVSS V3 rated as High - 7.4 severity.
  • CVSS V2 rated as Medium - 5.4 severity.
