ASP.NET Bad Practices: Compression Over Encrypted WebSocket Connection
Abstract
應用程式啟用了危險的壓縮。
Explanation
此程式碼將
DangerousEnableCompression 設定為 true，這會啟用 'permessage-deflate' WebSocket 擴充功能。當您透過加密連線啟用此壓縮時，會使應用程式易於受到 CRIME 和 BREACH 攻擊。範例 1：以下程式碼將
DangerousEnableCompression 設定為 true。
app.Run(async context => {
using var websocket = await context.WebSockets.AcceptWebSocketAsync(new WebSocketAcceptContext() { DangerousEnableCompression = true });
await websocket.SendAsync(...);
await websocket.ReceiveAsync(...);
await websocket.CloseAsync(WebSocketCloseStatus.NormalClosure, null, default);
});
