Wall Rose

Challenge

nc 34.80.190.155 30001

Instruction

You have a busybox shell running as user user
/home/user/rose.ko is a vulnerable kernel driver
Try exploiting /home/user/rose.ko to achieve privilege escalation
You may assumed that Busybox, the Linux kernel, and Qemu are not vulnerable.

Files

./share/rose.ko: The vulnerable driver
./src/rose.c: The source code of rose.c

Flag location

/home/user/flag

Notes

FG-KASLR is enabled
Your exploit should be kernel-agnostic. In other words, it should not rely on any kernel offsets
