CVE-2023-1863
📋 TL;DR
This SQL injection vulnerability in Eskom Water Metering Software allows attackers to execute arbitrary SQL commands, potentially leading to command line execution on the underlying system. It affects all versions before 23.04.06 of the water metering software, putting utility infrastructure at risk.
💻 Affected Systems
- Eskom Water Metering Software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to execute arbitrary commands on the server, manipulate water metering data, disrupt utility operations, and pivot to other network systems.
Likely Case
Data exfiltration, manipulation of water consumption records, and potential denial of service by corrupting database tables.
If Mitigated
Limited to database information disclosure if proper input validation and parameterized queries are implemented.
🎯 Exploit Status
The vulnerability allows SQL injection that can lead to command execution, suggesting the database has extended functionality or the application uses vulnerable stored procedures.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 23.04.06
Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-23-0225
Restart Required: Yes
Instructions:
1. Download version 23.04.06 from Eskom vendor portal. 2. Backup current installation and database. 3. Run installer for version 23.04.06. 4. Restart the water metering service. 5. Verify functionality.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to filter malicious requests.
Network Segmentation
allIsolate water metering systems from general network access and restrict to necessary connections only.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in application code.
- Disable unnecessary database functions like xp_cmdshell and limit database user permissions.
🔍 How to Verify
Check if Vulnerable:
Check software version in application settings or about dialog; if version is earlier than 23.04.06, system is vulnerable.Check Version:
Check application GUI or configuration files for version information (no standard CLI command provided).Verify Fix Applied:
Confirm version shows 23.04.06 or later in application interface and test SQL injection attempts are blocked.📡 Detection & Monitoring
