Release: VM Escape Exploit for Parallels Desktop Hypervisor (Pwn2Own 2021)
In April 2021 I participated in Pwn2Own Vancouvver competition as a single player, and successfully demonstrated a 0-day virtual machine escape exploit with code execution on Parallels hypervisor. Today I am finally releasing the exploit source code together with a technical walkthrough video talk that I gave on Zero Day Engineering livestream in November 2021.

Turning a boring file move into a privilege escalation on Mac | pwn.win
While poking around Parallels Desktop I found a script which is invoked by a setuid-root binary, which has the following snippet: local prl_dir="${usr_home}/Library/Parallels" if [ -e "$prl_dir" -a ! -d "$prl_dir" ]; then log warning "'${prl_dir}' is not a directory. Renaming it." mv -f "$prl_dir"{,~} continue fi Here ${usr_home} represents the home directory of the user for which Parallels Desktop is installed. The code says if ~/Library/Parallels exists and is not a directory then move it to ~/Library/Parallels~, presumably to back it up before creating this path as a directory.
