CVE-2020-7614
📋 TL;DR
CVE-2020-7614 is a command injection vulnerability in npm-programmatic versions through 0.0.12 that allows attackers to execute arbitrary commands on the host system. The vulnerability occurs because user-controlled input is passed directly to the exec() function without proper validation. This affects any application using the vulnerable npm-programmatic package.
💻 Affected Systems
- npm-programmatic
📦 What is this software?
Npm Programmatic by Npm Programmatic Project
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with remote code execution, allowing attackers to install malware, exfiltrate data, or pivot to other systems.
Likely Case
Local privilege escalation or arbitrary command execution within the application's context, potentially leading to data theft or service disruption.
If Mitigated
Limited impact if proper input validation and sandboxing are implemented, restricting command execution to safe operations.
🎯 Exploit Status
Exploitation is straightforward as it involves injecting shell commands into the vulnerable parameters.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.0.13 and later
Vendor Advisory: https://github.com/Manak/npm-programmatic/security/advisories
Restart Required: No
Instructions:
1. Update npm-programmatic to version 0.0.13 or later using 'npm update npm-programmatic'. 2. Verify the update with 'npm list npm-programmatic'. 3. Test application functionality.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for all parameters passed to npm-programmatic functions.
Replace with Safe Alternative
allReplace npm-programmatic with safer alternatives like child_process.spawn with proper argument escaping.
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user inputs that flow to npm-programmatic.
- Run the application with minimal privileges and in a sandboxed environment to limit potential damage.
🔍 How to Verify
Check if Vulnerable:
Check package.json or run 'npm list npm-programmatic' to see if version is 0.0.12 or earlier.Check Version:
npm list npm-programmatic | grep npm-programmaticVerify Fix Applied:
Verify npm-programmatic version is 0.0.13 or later using 'npm list npm-programmatic'.📡 Detection & Monitoring
