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

Complete system compromise with attacker gaining full control of the server, data exfiltration, and lateral movement within the network.

🟠

Likely Case

Remote code execution leading to data theft, service disruption, or cryptocurrency mining malware installation.

🟢

If Mitigated

Limited impact if proper input validation and sandboxing are implemented, though the vulnerability remains present.

🌐 Internet-Facing: HIGH - The vulnerability can be exploited remotely without authentication, making internet-facing applications extremely vulnerable.
🏢 Internal Only: HIGH - Even internal applications can be exploited by authenticated users or through other attack vectors.

🎯 Exploit Status

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

The vulnerability is demonstrated with a public proof-of-concept and requires minimal technical skill to exploit.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: None

Vendor Advisory: https://snyk.io/vuln/SNYK-JS-TSPROCESSPROMISES-1048334

Restart Required: Yes

Instructions:

1. Remove ts-process-promises from package.json. 2. Run npm uninstall ts-process-promises. 3. Find alternative packages for promise handling. 4. Restart all affected services.

🔧 Temporary Workarounds

Input Validation Wrapper

all

Create a wrapper function that validates all inputs before passing to ts-process-promises

// Implement strict input validation for all parameters passed to ts-process-promises functions

Sandbox Execution

all

Run the vulnerable code in a sandboxed environment with limited permissions

// Use Node.js vm module or containerization to isolate ts-process-promises execution

🧯 If You Can't Patch

  • Remove ts-process-promises entirely and replace with alternative promise handling libraries
  • Implement strict network segmentation to isolate affected systems and limit blast radius

🔍 How to Verify

Check if Vulnerable:

Check package.json for ts-process-promises dependency or run: npm list ts-process-promises

Check Version:

npm list ts-process-promises

Verify Fix Applied:

Verify ts-process-promises is no longer in package.json and npm list shows it's not installed

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution patterns
  • Suspicious child process spawns
  • Abnormal system command output in application logs

Network Indicators:

  • Unexpected outbound connections from application servers
  • Command and control traffic patterns

SIEM Query:

process.name:node AND (process.args:*ts-process-promises* OR process.args:*child_process.spawn* WITH suspicious parameters)
