📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized access to sensitive barangay resident data, modification of records, and potential privilege escalation to admin access.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, with database permissions restricted.
🎯 Exploit Status
Exploitation requires admin access to reach the vulnerable endpoint. SQL injection payloads can be crafted based on the public PoC.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
1. Check vendor website for updated version
2. If no patch available, implement workarounds
3. Manually fix vulnerable code by implementing parameterized queries
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Input Validation Filter
allImplement input validation to sanitize user inputs before processing
// PHP example: filter_var($_GET['param'], FILTER_SANITIZE_STRING);
🧯 If You Can't Patch
- Restrict access to /barangay_management/admin/ endpoint using IP whitelisting or VPN
- Implement database user with minimal permissions (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Test the /barangay_management/admin/?page=view_household endpoint with SQL injection payloads like ' OR '1'='1Check Version:
Check system version in admin panel or readme filesVerify Fix Applied:
Verify that parameterized queries are implemented and SQL injection payloads no longer work📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by SQL payloads
- Access to view_household endpoint with suspicious parameters
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) to the vulnerable endpoint
- Unusual database connection patterns
SIEM Query:
source="web_logs" AND uri="/barangay_management/admin/" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR '1'='1*")
