Access Control: gRPC Authentication Bypass

Java/JSP

Abstract

Google Remote Procedure Call (gRPC) Metadata 对象是通过不可信数据源创建的。

Explanation

Metadata 类通常用于存放 Google Remote Procedure Call (gRPC) 使用的基本协议的标头数据。在实现 io.grpc.ServerInterceptor 类时，应在 Metadata 对象传递到下一个 io.grpc.ServerCallHandler 对象之前对其进行验证。特别是当 Metadata 对象具有调用方身份时。

示例 1：以下代码显示了用作 gRPC Metadata 对象输入的用户可控数据，该对象在传递到下一个 io.grpc.ServerCallHandler 对象之前未经验证：


class PotentialAuthByPassInterceptor implements ServerInterceptor {
    @Override
    public <ReqT, RespT> ServerCall.Listener<ReqT> interceptCall(ServerCall<ReqT, RespT> call, Metadata metadata, ServerCallHandler<ReqT, RespT> next) {
        return Contexts.interceptCall(Context.current(), call, metadata, next);
    }
}
