// CVE-2025-43497 PoC - Conceptual Sandbox Escape // Note: This is a theoretical PoC for educational purposes only // The actual exploit requires specific macOS Tahoe vulnerabilities #include <stdio.h> #include <stdlib.h> #include <unistd.h> // Simulated vulnerable function int vulnerable_sandbox_check() { // Race condition or logic flaw in sandbox validation return 0; // Should return 1 to indicate sandbox violation } int main() { printf("CVE-2025-43497 macOS Tahoe Sandbox Escape PoC\n"); printf("Attempting to bypass sandbox restrictions...\n"); // Attempt to trigger sandbox escape condition if (vulnerable_sandbox_check() == 0) { printf("[+] Sandbox check passed - attempting escape\n"); // In real exploit: trigger specific syscall or IPC mechanism // to access resources outside sandbox scope // Example: Access restricted file system paths // system("/bin/cat /etc/passwd"); // Should be blocked printf("[+] Potential sandbox escape condition detected\n"); } else { printf("[-] Sandbox check failed - blocked\n"); } return 0; } /* Real-world exploitation notes: 1. Requires local access to macOS Tahoe system 2. Low-privileged app context 3. Target: macOS Tahoe < 26.1 4. Impact: Limited confidentiality/integrity breach */
