Apache bRPC（版本低于 1.18.0）在所有平台上存在流式 RPC 路径缺少身份验证的漏洞。当服务器配置了身份验证器（Authenticator）时，远程攻击者可绕过服务器身份验证机制，注入或投递流式数据帧。 根本原因： 当启用身份验证时，流式 RPC 数据帧由流式解析器（ ）直接消费，未经过 的身份验证钩子。因此，未经验证的客户端可交换数据帧而无需通过身份验证。此外，服务器接受的流式连接是“惰性绑定”的：它仅在遇到第一个携带其 ID 的数据帧时才完成绑定。这导致攻击者可能从不同于创建该流的套接字（soc

Vulnerability Title
Apache bRPC: Missing Authentication for Streaming RPC Frames
来源: CVE Program / CVE List V5
Vulnerability Description
Missing authentication in the streaming RPC path of Apache bRPC (version < 1.18.0) on all platforms allows a remote attacker to bypass server authentication and inject or deliver streaming frames, when a server is configured with an Authenticator.
Root Cause:
When authentication is configured, streaming RPC frames are consumed directly by the streaming parser (ParseStreamingMessage) and never pass through InputMessenger's authentication hook, so an unauthenticated peer can exchange frames without being authenticated. In addition, a server-accepted stream is bound lazily to the first frame that happens to carry its id, so a stream could accept a frame carrying its id from a socket other than the socket that created the stream.
Affected Scenarios:
A bRPC server configured with authentication that serves streaming RPC from an untrusted network, or a deployment where a foreign connection can impersonate a stream by id, can be made to accept unauthorized streaming frames.
How to Fix:
Upgrade bRPC to 1.18.0, which fixes this issue, or apply the patch in PR https://github.com/apache/brpc/pull/3481.
Note:
The fix rejects streaming frames on server sockets when configured authentication has not completed, and keeps server-accepted streams bound to the socket of their creating RPC and rejects frames arriving from another socket. Authenticated streaming RPC behavior and the wire format are unchanged; only unauthenticated or foreign-socket frames are now rejected.
