界: Security Features

軟體安全性並非安全性軟體。我們關注驗證、Access Control、保密性、加密以及權限管理之類的主題。

Access Control: gRPC Fail Open

Abstract
儘管驗證失敗,Google 遠端程序呼叫 (gRPC) Metadata 物件仍被接受。
Explanation
Metadata 類別通常用於存放 Google 遠端程序呼叫 (gRPC) 所用之基礎通訊協定的標頭資料。在實作 io.grpc.ServerInterceptor 類別時,應該驗證 Metadata 物件,如果擲回異常,則傳回錯誤。

範例 1:以下程式碼顯示使用者可控資料被當成 gRPC Metadata 物件的輸入使用,這個物件在擷取異常狀況後,傳遞到下一個 io.grpc.ServerCallHandler 物件。


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