CVE-2023-42931 is a privilege escalation vulnerability in macOS Ventura, Sonoma, and Monterey, where a process may gain administrative privileges without proper authentication due to insufficient privilege checks. The vulnerability was addressed by Apple with improved checks in macOS Ventura 13.6.3, Sonoma 14.2, and Monterey 12.7.2.

This repository contains a local privilege escalation (LPE) exploit for macOS versions 12.0-12.7.1, 13.0-13.6.2, and 14.0-14.1.2, targeting CVE-2023-42931. The main exploit logic is implemented in 'PoC.sh', a Bash script that creates a C payload ('/tmp/suidshell.c'), compiles it to a setuid binary ('/tmp/suidshell'), and leverages macOS disk utilities to mount the root filesystem with the 'noowners' flag. This allows the script to overwrite the '.file' on the root filesystem with the setuid shell, set its permissions to 4755, and then execute it to obtain a root shell. The exploit requires local access and the ability to execute shell scripts and compile code. The repository also includes a README with usage instructions and a LICENSE file. The exploit is operational and provides a working root shell if successful.
This repository contains a local privilege escalation exploit for macOS (Monterey, Ventura, Sonoma) targeting CVE-2023-42931. The main exploit script (PoC.py) is written in Python and automates the process of gaining root privileges by abusing the 'diskutil' command to manipulate filesystem mount options. The exploit workflow is as follows: (1) a C source file for a setuid root shell is written to /tmp/suidshell.c and compiled; (2) the attacker mounts a target disk with the 'noowners' option to bypass file ownership restrictions; (3) permissions on a special file (/.file) are modified to allow writing; (4) the setuid shell binary is copied to /.file and its permissions are set to setuid root; (5) the disk is remounted with 'owners,suid' options to re-enable setuid execution; (6) the setuid shell is executed, granting a root shell. The repository consists of the exploit script and a README.md that documents the vulnerability, usage instructions, and credits. The exploit is operational and provides a working root shell payload, but is not part of a larger framework.
