Dockerfile Misconfiguration: Default User Privilege

Docker

Abstract

Dockerfile は USER を指定しないため、デフォルトでは root ユーザーで実行されます。

Explanation

Dockerfile が USER を指定していない場合、デフォルトでは Docker コンテナーはスーパーユーザー権限で実行されます。これらのスーパーユーザー権限は、コンテナー内で実行されているコードに伝達されます。これは通常、必要以上の権限です。スーパーユーザー権限で Docker コンテナーを実行すると、攻撃対象領域が広がり、攻撃者による深刻な形式の悪用が可能になるおそれがあります。
