Dirtyc0w Docker POC
The Dirtyc0w Docker POC is a proof-of-concept demonstration that exploits the CVE-2016-5195 kernel vulnerability (known as Dirty COW) within containerized environments. The tool operates by leveraging the race condition vulnerability in the Linux kernel's memory subsystem to achieve privilege escalation from within a Docker container. It specifically targets standard nginx Docker images by adding a non-root user named "hacker" to demonstrate the exploit's effectiveness. The POC serves as an educational resource for understanding container security vulnerabilities and demonstrates how kernel-level exploits can bypass container isolation mechanisms. It includes practical examples of how the Dirty COW vulnerability can be exploited in containerized environments. Additionally, the tool provides guidance on implementing security mitigations, including the use of AppArmor profiles to prevent such attacks without requiring kernel patches. This makes it valuable for security professionals learning about container security hardening techniques.
