Exploits for CVE-2023-27327 and CVE-2023-27328

parallels-plist-escape

This repository contains exploits for CVE-2023-27327 and CVE-2023-27328, which can be used together to escape a Parallels Desktop virtual machine, prior to Parallels Desktop 18.1.1.

It also contains code for a required kernel module, in prl_mod, which can be used to send arbitrary Toolgate requests (< opcode 0x8000) from userland, using a proc entry created at /proc/driver/prl_tg_pwn.

Requirements

• Root in the guest so you can load the kernel module
• Parallels Tools installed - this is not strictly required if we have root in the guest, but the code here assumes it's present
• At least one share mounted into the VM, it doesn't matter where this is on the host

Running the exploit

Build and load the kernel module:

cd prl_mod
make -f Makefile.kmods
sudo insmod ./prl_tg_pwn/Toolgate/Guest/Linux/prl_tg/prl_tg_pwn.ko

Run the exploit:

cd ..
pip install -r requirements.txt
./3_full_chain.py
