CyberRota Analysis
AI-GeneratedVersions of Netty prior to 4.2.18.Final are vulnerable due to an incomplete hostname verification fix in the QUIC certificate verification process, which allows attackers on the network path to present fraudulent certificate chains that bypass hostname authentication. This vulnerability can lead to man-in-the-middle attacks, compromising the security of QUIC clients. Organizations utilizing affected Netty versions, especially those handling sensitive data or operating in high-security environments, should prioritize updating to mitigate potential risks.

Original NVD Description
Netty versions from 4.2.11.Final before 4.2.18.Final contain an incomplete hostname verification fix in the QUIC certificate verification path when using a plain X509TrustManager. The BoringSSLCertificateVerifyCallback discards the SSLEngine for plain trust managers, preventing endpoint identification from running even when HTTPS verification is configured. Attackers on the network path can present a certificate chain for the wrong hostname that the plain trust manager accepts, bypassing hostname authentication for QUIC clients.
