This repository contains a working exploit for CVE-2023-32364, a macOS app sandbox escape vulnerability. The exploit is implemented as a Swift-based macOS application with a key payload in the bash script 'appsbx_escape_exploit.sh'. The exploit works by creating a malicious .app bundle, using devfs to bypass quarantine checks via symlinks, and modifying the Info.plist to inject an LSEnvironment variable. This allows the attacker to execute arbitrary code outside the sandbox by leveraging the BASH_ENV environment variable when launching /bin/bash. The exploit demonstrates successful sandbox escape by creating a file (~/Desktop/pwned) on the user's desktop containing system information. The repository includes Swift source files for the app, a C helper for command execution, and the main bash exploit script. The exploit targets macOS 13.0+ systems vulnerable to CVE-2023-32364 and requires execution from a sandboxed app context. No network endpoints are involved; the attack vector is local privilege escalation via sandbox escape.
