CVE-2017-11494
📋 TL;DR
This CVE describes a SQL injection vulnerability in SOL.Connect ISET-mpp meter software versions 1.2.4.2 and earlier. Attackers can execute arbitrary SQL commands via the user parameter during login, potentially compromising the system. Organizations using affected versions of this energy metering software are at risk.
💻 Affected Systems
- SOL.Connect ISET-mpp meter
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary SQL commands, potentially leading to data theft, authentication bypass, remote code execution, or system takeover.
Likely Case
Authentication bypass leading to unauthorized access to the metering system, potential data manipulation or extraction of sensitive information.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection, though system may still be vulnerable to other attacks.
🎯 Exploit Status
Exploit code is publicly available on Exploit-DB (ID 42408). The vulnerability requires no authentication and has simple exploitation vectors.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No vendor advisory found in provided references
Restart Required: No
Instructions:
No official patch available. Upgrade to version above 1.2.4.2 if available, otherwise implement workarounds.
🔧 Temporary Workarounds
Implement Input Validation
allAdd server-side input validation to sanitize user parameter in login requests
# Application-specific implementation required
# Example: Validate user parameter contains only alphanumeric characters
Use Parameterized Queries
allModify login SQL queries to use parameterized statements instead of string concatenation
# Application code modification required
# Example: Use prepared statements with parameter binding
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement a web application firewall (WAF) with SQL injection protection rules
🔍 How to Verify
Check if Vulnerable:
Test login functionality with SQL injection payloads in the user parameter (e.g., ' OR '1'='1)Check Version:
Check software version in administration interface or configuration filesVerify Fix Applied:
Attempt SQL injection attacks against the login endpoint and verify they are blocked or properly handled📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in login attempts
- Multiple failed login attempts with SQL-like patterns
- Successful logins from unexpected IP addresses
Network Indicators:
- HTTP POST requests to login endpoint containing SQL keywords in parameters
- Unusual database query patterns following login attempts
SIEM Query:
source="web_logs" AND (uri="/login" OR uri="*/login*") AND (user="*OR*" OR user="*UNION*" OR user="*SELECT*" OR user="*INSERT*" OR user="*DELETE*")
