CyberRota Analysis
AI-GeneratedThe vulnerability affects the Apache CXF Netty-based HTTP client transport, which fails to verify that the hostname in the server's TLS certificate matches the intended host, allowing network attackers to intercept traffic and impersonate services. This could lead to unauthorized access to sensitive data, including credentials, making it critical for organizations using affected versions of Exchange and Apache CXF to prioritize upgrades to versions 4.2.4, 4.1.9, or 3.6.13. Immediate action is essential to mitigate the risk of man-in-the-middle attacks.
Original NVD Description
In Apache CXF, the Netty-based HTTP client transport (cxf-rt-transports-http-netty-client) did not verify that the hostname in the server’s TLS certificate matched the host being called. This applied over both HTTP/1.1 and HTTP/2, even when disableCNCheck was left at its default value of false. The certificate chain was validated against the configured trust store, but the endpoint’s identity was not. A network attacker able to intercept traffic could present any certificate trusted by the client, such as a publicly issued certificate for a domain they control, and impersonate the target service. They could then read or modify the exchanged messages, including credentials. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
