Protection Mechanism Failure

github.com/envoyproxy/envoy is vulnerable to Protection Mechanism Failure. The vulnerability is due to accepting and forwarding client data before a successful 2xx response in TCP proxy mode, which allows an attacker to cause desynchronization when upstream proxies reject the CONNECT request...

GHSA-RJ35-4M94-77JH Envoy forwards early CONNECT data in TCP proxy mode

Summary Forwarding of early CONNECT data in TCP proxy mode. Details Per RFC 7231-4.3.6 the sender of CONNECT and all inbound proxies switch to tunnel mode only after receiving 2xx response. However in TCP proxy mode, Envoy accepts client data before it has issued a 2xx response and eagerly proxie...
