CVE-2022-30129
📋 TL;DR
This vulnerability allows remote code execution in Visual Studio Code through argument injection in the 'code' command-line tool. Attackers can craft malicious arguments that execute arbitrary commands when developers open files or URLs. All users running vulnerable versions of VS Code are affected.
💻 Affected Systems
- Visual Studio Code
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the developer's machine, allowing data theft, lateral movement, and persistence.
Likely Case
Local privilege escalation leading to execution of malicious code in the context of the current user, potentially stealing credentials and sensitive development artifacts.
If Mitigated
Limited impact with proper execution controls and network segmentation, potentially only affecting isolated development environments.
🎯 Exploit Status
Exploitation requires user interaction but is straightforward once the malicious argument is crafted.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.67.0 and later
Vendor Advisory: https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2022-30129
Restart Required: Yes
Instructions:
1. Open VS Code. 2. Go to Help > Check for Updates. 3. Install update to version 1.67.0 or later. 4. Restart VS Code.
🔧 Temporary Workarounds
Disable automatic file opening
allPrevent VS Code from automatically opening files via command-line arguments
Use alternative editors for untrusted files
allOpen files from untrusted sources with basic text editors instead of VS Code
🧯 If You Can't Patch
- Restrict execution of 'code' command to trusted users only
- Implement application whitelisting to prevent unauthorized code execution
🔍 How to Verify
Check if Vulnerable:
Check VS Code version via Help > About or run 'code --version' in terminalCheck Version:
code --versionVerify Fix Applied:
Confirm version is 1.67.0 or higher using 'code --version' command📡 Detection & Monitoring
