Patch Version: Not available
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch exists, implement workarounds immediately. 3. Consider migrating to alternative inventory systems.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize uemail parameter before processing SQL queries.
Modify /user.php to validate email format and escape special characters
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the uemail parameter.
Configure WAF to detect and block SQL injection attempts on /user.php
🧯 If You Can't Patch
- Implement network segmentation to isolate the inventory system from critical assets.
- Disable or restrict access to /user.php if not required for business operations.
🔍 How to Verify
Check if Vulnerable:
Test the uemail parameter in /user.php with SQL injection payloads like ' OR '1'='1.Check Version:
Check system documentation or configuration files for version information.Verify Fix Applied:
Retest with SQL injection payloads after implementing fixes; successful attacks should be blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts with SQL syntax in parameters
Network Indicators:
- HTTP requests to /user.php containing SQL keywords in uemail parameter
SIEM Query:
source="web_logs" AND uri_path="/user.php" AND (param="uemail" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and)")
