Vulnerability from cnvd

Title: Envoy存在未明漏洞（CNVD-2021-07242）

Description:

Envoy是一款开源的分布式代理服务器。

Envoy 1.16.1之前版本存在安全漏洞，该漏洞源于记录一个不正确的下游地址，因为它只考虑直接连接的对等端，而未考虑代理协议报头中的信息。这将影响将tcp-proxy作为网络过滤器(而非HTTP过滤器)的情况。目前没有详细的漏洞细节提供。

Summary

Envoy before 1.16.1 logs an incorrect downstream address because it considers only the directly connected peer, not the information in the proxy protocol header. This affects situations with tcp-proxy as the network filter (not HTTP filters).
