This repository provides a local privilege escalation exploit for CVE-2023-42860, targeting macOS versions prior to 13.3. The exploit leverages a race condition during the installation of macOS Ventura using the InstallAssistant.pkg. By creating a symlink from a SIP-protected file (default: /Library/Application Support/com.apple.TCC/TCC.db) to a file used by the installer (/Applications/Install macOS Ventura.app/Contents/SharedSupport/SharedSupport.dmg), the exploit removes the 'restricted' flag, allowing the attacker to modify the protected file. The repository contains: - 'exploit.c': A C program that automates the race condition and symlink creation. - 'exploit.sh': A Bash script alternative to the C exploit, monitoring the installer log and creating the symlink at the right moment. - 'resettcc.sh': A helper script to reset the TCC database and restart the tccd service. - 'README.md': Documentation with usage instructions and references. The exploit requires root privileges and is intended for research purposes. No network endpoints are involved; all actions are performed locally on the target system.
