Fuse: privilege escalation via excessive /etc/passwd permissions

A container privilege escalation flaw was found in certain Fuse images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.

Red Hat Fuse 安全漏洞

Red Hat Fuse是美国红帽（Red Hat）公司的一套基于Apache Camel的开源分布式集成平台。该平台能够提供标准化的方法、基础结构和工具集成服务、微服务和应用程序组件。 Red Hat Fuse存在安全漏洞，该漏洞源于构建时创建的/etc/passwd文件具有组可写权限，可能导致攻击者在容器内执行命令并修改该文件，从而获得完整的root权限。
