CVE-2025-43348 Apple macOS Gatekeeper安全绕过漏洞

// CVE-2025-43348 PoC - Gatekeeper Bypass Demonstration // This is a conceptual proof-of-concept for educational purposes only // Step 1: Create a malicious application bundle with manipulated Info.plist const maliciousApp = { bundleIdentifier: 'com.apple.legitimate.app', executablePath: './MaliciousBinary', infoPlist: { 'CFBundleIdentifier': 'com.apple.legitimate.app', 'CFBundleName': 'System Update', 'LSMinimumSystemVersion': '10.15.0' } }; // Step 2: Exploit code signing validation logic flaw // The vulnerability allows bypassing Gatekeeper checks through: // - Manipulation of extended attributes // - Special characters in bundle paths // - Code signature inconsistencies function exploitGatekeeperBypass() { // Remove quarantine extended attribute // This is a simplified representation of the bypass technique console.log('Attempting to remove quarantine attribute...'); // Modify application bundle to appear legitimate console.log('Crafting application with legitimate-looking signature...'); // Execute the malicious binary console.log('Executing payload with Gatekeeper bypassed...'); } // Step 3: Payload execution const payload = ` #!/bin/bash # Payload to be executed after successful bypass # This would contain the actual malicious commands `; // Note: Actual exploitation requires specific conditions and macOS version console.log('PoC for CVE-2025-43348 - Gatekeeper Logic Bypass');
