CVE-2023-29118

9.6 CRITICAL

📋 TL;DR

This vulnerability allows unauthenticated attackers to execute arbitrary SQL commands on the Waybox Enel X web management application's internal database via the /admin/versions.php endpoint. This affects all organizations using vulnerable versions of the Waybox Enel X web management application for electric vehicle charging infrastructure management.

💻 Affected Systems

Products:
  • Waybox Enel X web management application
Versions: All versions prior to the security bulletin release
Operating Systems: Linux-based systems running the Waybox application
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default installation and configuration of the Waybox web management application.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of the database leading to data theft, manipulation of charging infrastructure controls, and potential lateral movement to other systems.

🟠

Likely Case

Extraction of sensitive data including user credentials, payment information, and operational data from the charging management system.

🟢

If Mitigated

Limited impact if proper network segmentation and database access controls are implemented, though SQL injection would still be possible.

🌐 Internet-Facing: HIGH - The vulnerable endpoint is accessible via web interface and requires no authentication.
🏢 Internal Only: HIGH - Even if not internet-facing, internal attackers or compromised systems could exploit this vulnerability.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

SQL injection vulnerabilities are well-understood and easily weaponized. The unauthenticated nature makes exploitation trivial for attackers with network access.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version specified in Waybox-3-Security-Bulletin-06-2024-V1.pdf

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 update from Enel X support portal. 2. Apply the patch following vendor instructions. 3. Restart the Waybox application service. 4. Verify the /admin/versions.php endpoint no longer accepts arbitrary SQL commands.

🔧 Temporary Workarounds

Block vulnerable endpoint

all

Temporarily block access to the /admin/versions.php endpoint using web server configuration or firewall rules.

# Apache: RewriteRule ^/admin/versions\.php$ - [F]
# Nginx: location ~ ^/admin/versions\.php$ { deny all; }
# Firewall: iptables -A INPUT -p tcp --dport 80 -m string --string "/admin/versions.php" --algo bm -j DROP

Implement WAF rules

all

Deploy web application firewall rules to detect and block SQL injection attempts.

# ModSecurity rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"

🧯 If You Can't Patch

  • Isolate the Waybox management interface to a dedicated VLAN with strict access controls.
  • Implement database-level protections including prepared statements and input validation in the application code.

🔍 How to Verify

Check if Vulnerable:

Test if the /admin/versions.php endpoint accepts SQL injection payloads. Example: curl -X POST 'http://[target]/admin/versions.php' --data 'parameter=1' OR '1'='1'

Check Version:

Check the application version via the web interface or consult the vendor documentation for version identification.

Verify Fix Applied:

Attempt the same SQL injection test after patching - it should return an error or no database response.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts followed by SQL injection patterns
  • Access to /admin/versions.php with suspicious parameters

Network Indicators:

  • HTTP POST requests to /admin/versions.php containing SQL keywords (SELECT, UNION, INSERT, etc.)
  • Unusual database connection patterns from the web server

SIEM Query:

source="web_logs" AND uri="/admin/versions.php" AND (request_body CONTAINS "UNION" OR request_body CONTAINS "SELECT" OR request_body CONTAINS "INSERT")
