Dockerfile Misconfiguration: Sensitive Host Directory

Docker

Abstract

顯示敏感的主機目錄可能會使攻擊者能存取重要的系統資訊

Explanation

您可以使用 docker inspect 和 history 指令從公開的 Docker 映像檔重建構 Dockerfile，或者透過第三方工具自動執行此程序。如果使用 ADD/COPY 指令新增了敏感資訊，則攻擊者可以重新建立每個 docker 層以取得該資訊。

使用 Volumes 也可能公開敏感目錄。如果需要使用 Volumes 來保存資料，請避免掛接敏感目錄。
