CVE-2024-57066
📋 TL;DR
This vulnerability allows attackers to perform prototype pollution in the lib.deep function of @ndhoule/defaults library version 2.0.1, potentially causing Denial of Service (DoS) by supplying a specially crafted payload. Any application using this vulnerable version of the library is affected, particularly Node.js applications that handle untrusted user input.

⚠️ Risk & Real-World Impact
Worst Case
Complete application crash leading to sustained downtime, potentially affecting multiple services if the library is widely used in a microservices architecture.
Likely Case
Application instability or crashes when processing malicious input, resulting in intermittent service disruption.
If Mitigated
Minimal impact with proper input validation and sanitization in place before data reaches the vulnerable function.
🎯 Exploit Status
Exploitation requires understanding of prototype pollution techniques and ability to craft specific payloads that trigger the vulnerability in the lib.deep function.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.2 or later
Vendor Advisory: https://github.com/ndhoule/defaults
Restart Required: No
Instructions:
1. Check current version: npm list @ndhoule/defaults
2. Update package: npm update @ndhoule/defaults
3. Verify update: npm list @ndhoule/defaults should show version 2.0.2 or higher
🔧 Temporary Workarounds
Input Validation Wrapper
allImplement input validation and sanitization before passing data to the lib.deep function
🧯 If You Can't Patch
- Implement strict input validation to prevent malicious payloads from reaching the vulnerable function
- Monitor application logs for unusual patterns or crashes that might indicate exploitation attempts
