CVE-2022-32210Public exploitNetwork attack vector

HTTPS traffic interception via missing certificate verification

Published Jul 14, 2022 · Updated Aug 3, 2024

Improper certificate validation in Node.js Undici 4.8.2 through 5.5.0 allows attackers to intercept HTTPS traffic via ProxyAgent. ProxyAgent omits remote-server certificate verification and, with an HTTP proxy, sends nominal HTTPS traffic in plaintext to that proxy. Exploitation requires ProxyAgent on TLS connections and control of the configured proxy or a position on the client-to-server network path.
