Dockerfile Misconfiguration: Privileged Port

Docker

Abstract

Dockerfile 打开小于 1024 的容器端口。

Explanation

默认情况下，Docker 允许将特权端口绑定到容器，如果用户未声明端口，则 Docker 会将容器端口映射到 49153-65535 范围内的某个端口。在很多情况下，运行服务需要打开某些端口，随着时间的推移，开放的端口数可能会越来越多。开放的端口会增加攻击面，特别是对于以更高权限运行的服务。确保只打开运行该特定服务所需的端口。当服务不要求较高的权限时，在特权端口范围以外的端口上运行这些服务。
