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。

Unauthenticated Service: Redis

Java/JSP

Abstract

應用程式會初始化 Redis 用戶端，但不設定任何認證。

Explanation

未經驗證的 Redis 伺服器可能成為攻擊者的目標，透過危害伺服器達到涉足您內部網路的目的。

可能會針對 Redis 伺服器使用不同的攻擊方式，以對其基礎作業系統執行任意程式碼。例如，攻擊者可以使用 Redis 指令，將 Web Shell 寫入 Web 根目錄。用來儲存物件時，攻擊者也可能針對不同的語言 (例如 Java、Python、Ruby、PHP 等) 儲存還原序列化裝載，以便對還原序列化端點執行遠端程式碼。

請注意，即使沒有在外部暴露 Redis 伺服器，外部攻擊者仍可能透過同一網路上任意應用程式內的 Server-Side Request Forgery 弱點對其進行存取。例如，Redis 伺服器可能成為使用 HTTP 或 Gopher 通訊協定的攻擊者。

由於 Redis 的特性，若無法從外部保護 Redis 連接埠，可能會對安全性有較大的影響。例如，外部攻擊者會使用單一 FLUSHALL 指令來刪除整個資料集。最近，有關於惡意攻擊網際網路上公開執行的不安全 Redis 實例的報告。攻擊者刪除了資料庫，並要求支付贖金才會加以還原。
