Dockerfile Misconfiguration: Sensitive Host Directory

Docker

Abstract

機密性の高いホストディレクトリを明らかにすると、攻撃者が重要なシステム情報にアクセスできる可能性があります。

Explanation

docker inspect コマンドと docker history コマンドを使用するか、サードパーティのツールを使用してこのプロセスを自動化することにより、公開されている docker イメージから Dockerfile を再構築できます。ADD/COPY コマンドを使用して機密情報が追加された場合、攻撃者は各 docker レイヤーを再作成してその情報を取得できます。

Volumes を使用した場合も、機密ディレクトリが公開される可能性があります。Volumes を使用してデータを永続化する必要がある場合は、機密性の高いディレクトリのマウントを避けてください。
