Loading vulnerability…
A local privilege escalation vulnerability exists in Parallels Desktop's Updater service. The flaw is due to improper handling of symbolic links, allowing a local attacker to create a symlink that the Updater service will follow, resulting in the movement of arbitrary files. This can be exploited to escalate privileges and execute code as root.

This repository contains a proof-of-concept (PoC) exploit for CVE-2023-50226, a local privilege escalation vulnerability in Parallels Desktop for macOS versions prior to 18.3.2. The exploit is implemented as a Bash script (poc.sh) that abuses the prl_update_helper setuid binary to move a symlink into /etc/sudoers.d, effectively granting the current user passwordless sudo access. The script first injects a sudoers entry into /var/log/install.log, manipulates symlinks in the user's Library directory, and then uses prl_update_helper to move the symlink into the sudoers.d directory. If successful, the script demonstrates root access by creating a file at /tmp/pwned. The repository is structured simply, with a README describing the exploit and the main exploit script. The attack vector is local, requiring shell access to the target system.
