🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameter validation to /logout.php to sanitize the 'uname' parameter
Edit /logout.php and add: $uname = mysqli_real_escape_string($connection, $_GET['uname']);
Web Application Firewall Rule
allBlock SQL injection patterns targeting /logout.php
WAF rule: deny requests to /logout.php containing SQL keywords in parameters
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict network access controls
- Implement database-level protections: use least privilege accounts, enable audit logging
🔍 How to Verify
Check if Vulnerable:
Test /logout.php?uname=test' OR '1'='1 and observe if SQL error occurs or unexpected behaviorCheck Version:
Check application files for version information or review installation documentationVerify Fix Applied:
Test with same payload after applying workarounds - should return proper error or no SQL execution📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from web server IP
- Multiple failed logout attempts with SQL-like parameters
Network Indicators:
- HTTP requests to /logout.php containing SQL keywords (UNION, SELECT, etc.) in parameters
- Abnormal database traffic patterns from web server
SIEM Query:
source="web_logs" AND uri="/logout.php" AND (param="*UNION*" OR param="*SELECT*" OR param="*OR '1'='1*")
