CVE-2023-29120
📋 TL;DR
CVE-2023-29120 is a critical OS command injection vulnerability in Waybox Enel X web management applications that allows authenticated attackers to execute arbitrary commands with administrator privileges. This affects organizations using Waybox systems for electric vehicle charging infrastructure management. Attackers can gain complete control over affected systems.
💻 Affected Systems
- Waybox Enel X web management application
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary OS commands, steal sensitive data, deploy ransomware, pivot to internal networks, and cause physical disruption to charging infrastructure.
Likely Case
Attackers gain administrative access to Waybox systems, potentially disrupting charging operations, stealing customer data, and using compromised systems as footholds for further attacks.
If Mitigated
With proper network segmentation and access controls, impact limited to isolated charging management systems without lateral movement to critical infrastructure.
🎯 Exploit Status
Exploitation requires authenticated access but command injection vulnerabilities are typically easy to exploit once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version specified in Waybox-3-Security-Bulletin-06-2024-V1
Vendor Advisory: https://support-emobility.enelx.com/content/dam/enelxmobility/italia/documenti/manuali-schede-tecniche/Waybox-3-Security-Bulletin-06-2024-V1.pdf
Restart Required: Yes
Instructions:
1. Download the security patch from Enel X support portal. 2. Apply the patch following vendor instructions. 3. Restart the Waybox system. 4. Verify patch installation.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Waybox management interfaces from internet and restrict access to authorized IPs only
Access Control Hardening
allImplement strong authentication, multi-factor authentication, and least privilege access
🧯 If You Can't Patch
- Immediately isolate Waybox systems from internet and restrict network access to management interfaces
- Implement strict monitoring for command execution attempts and unusual administrative activity
🔍 How to Verify
Check if Vulnerable:
Check Waybox version against security bulletin. Review system logs for command injection attempts.Check Version:
Check system web interface or consult vendor documentation for version informationVerify Fix Applied:
Verify patch version installation and test that command injection attempts are properly sanitized/blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Multiple failed authentication attempts followed by successful login
- Suspicious process creation from web application
Network Indicators:
- Unusual outbound connections from Waybox systems
- Traffic to known malicious IPs
- Unexpected protocol usage
