CVE-2014-9733
📋 TL;DR
This vulnerability in nw.js (formerly node-webkit) allows remote attackers to simulate user input events in normal frames, potentially enabling unauthorized actions. It affects applications built with nw.js versions before 0.11.5. Attackers could exploit this to perform actions on behalf of users without their consent.
💻 Affected Systems
- nw.js (formerly node-webkit)
📦 What is this software?
Nw.js by Nwjs
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the application allowing remote code execution, data theft, or unauthorized system access depending on application functionality.
Likely Case
Unauthorized actions within the application such as clicking buttons, submitting forms, or navigating to malicious sites without user interaction.
If Mitigated
Limited impact if application runs in sandboxed environment with minimal privileges and input validation.
🎯 Exploit Status
The vulnerability description suggests remote exploitation via unknown vectors, indicating potential for easy exploitation once vectors are discovered.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.11.5 and later
Vendor Advisory: https://github.com/nwjs/nw.js/blob/nw11/CHANGELOG.md
Restart Required: Yes
Instructions:
1. Update nw.js to version 0.11.5 or later. 2. Rebuild your application with the updated nw.js version. 3. Redeploy the updated application to all affected systems.
🔧 Temporary Workarounds
Application Sandboxing
allRun nw.js applications in restricted environments with minimal privileges
Network Segmentation
allIsolate nw.js applications from untrusted networks and internet access
🧯 If You Can't Patch
- Isolate affected applications in network segments with no internet access
- Implement application-level input validation and event filtering
🔍 How to Verify
Check if Vulnerable:
Check nw.js version in application dependencies or runtime. Versions below 0.11.5 are vulnerable.
Check Version:
Check package.json for nw.js version or run application with --version flag if supported
Verify Fix Applied:
Verify nw.js version is 0.11.5 or higher after update.
