Openshift/builder: path traversal allows command injection in privileged buildcontainer using docker build strategy

A flaw was found in openshift/builder. This vulnerability allows command injection via path traversal, where a malicious user can execute arbitrary commands on the OpenShift node running the builder container. When using the “Docker” strategy, executable files inside the privileged build container can be overridden using the `spec.source.secrets.secret.destinationDir` attribute of the `BuildConfig` definition. An attacker running code in a privileged container could escalate their permissions on the node running the container.

Red Hat OpenShift Container Platform 安全漏洞

Red Hat OpenShift Container Platform是美国红帽（Red Hat）公司的一套可帮助企业在物理、虚拟和公共云基础架构之间开发、部署和管理现有基于容器的应用程序的应用平台。 Red Hat OpenShift Container Platform 4存在安全漏洞，该漏洞源于openshift/builder允许通过路径穿越进行命令注入，恶意用户可以在运行构建器容器的OpenShift节点上执行任意命令。
