CVE-2024-22020

6.5 MEDIUM

📋 TL;DR

This Node.js vulnerability allows attackers to bypass network import restrictions by embedding non-network imports in data URLs, potentially leading to arbitrary code execution. It affects developers and servers using vulnerable Node.js versions, compromising system security when exploited.

💻 Affected Systems

Products:
  • Node.js
Versions: Specific versions not provided in CVE description, but likely affects multiple recent versions
Operating Systems: All platforms running Node.js
Default Config Vulnerable: ⚠️ Yes
Notes: Affects applications using network imports with data URL handling

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete system compromise, data theft, or ransomware deployment

🟠

Likely Case

Server compromise allowing data exfiltration or lateral movement within the network

🟢

If Mitigated

Import failures or application errors when malicious data URLs are blocked

🌐 Internet-Facing: HIGH - Web servers and APIs using Node.js are directly exposed to exploitation
🏢 Internal Only: MEDIUM - Internal applications could be exploited through phishing or compromised internal systems

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires crafting malicious data URLs in network imports

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Node.js security releases for specific version

Vendor Advisory: https://nodejs.org/en/blog/vulnerability

Restart Required: Yes

Instructions:

1. Check current Node.js version. 2. Update to latest patched version. 3. Restart all Node.js applications. 4. Test application functionality.

🔧 Temporary Workarounds

Disable data URLs in network imports

all

Configure Node.js to reject data URLs in network import contexts

Configure application to validate and reject data:// URLs in import statements

Implement input validation

all

Add validation to reject or sanitize data URLs in user-controlled import paths

Implement middleware or pre-processing to detect and block data:// scheme imports

🧯 If You Can't Patch

  • Implement strict Content Security Policies to restrict data URL usage
  • Use network segmentation to isolate Node.js applications from critical systems

🔍 How to Verify

Check if Vulnerable:

Check if application processes network imports that could contain data URLs

Check Version:

node --version

Verify Fix Applied:

Test with crafted data URL imports to ensure they are rejected

📡 Detection & Monitoring

Log Indicators:

  • Unusual import failures
  • Data URL patterns in import statements
  • Unexpected process spawns

Network Indicators:

  • Data URL patterns in HTTP requests
  • Unexpected outbound connections after import

SIEM Query:

search 'data://' in application logs OR detect unusual child_process spawn events
