Withdrawn Advisory
This advisory has been withdrawn because the underlying vulnerability only concerns Red Hat's Hot Rod client, which is not in one of the GitHub Advisory Database's supported ecosystems. This link is maintained to preserve external references.
Original Description
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.
In the interim users are advised to enable host name validation in their configurations. See https://github.com/netty/netty/issues/8537 for details on the forthcoming change in default behavior.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a low impact on the integrity of the data.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
