⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to theft of all banking data, financial fraud, and potential remote code execution on the database server.
Likely Case
Authentication bypass allowing unauthorized access to staff/admin functions, data exfiltration of customer banking information.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
SQL injection in login pages is commonly exploited. The GitHub issue shows the vulnerable code pattern.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Review the vulnerable staff_login.php file
2. Replace raw SQL queries with parameterized prepared statements
3. Implement proper input validation and sanitization
4. Test the login functionality thoroughly
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious payloads
Input Validation Filter
allAdd server-side input validation to reject SQL special characters in login fields
// PHP example: if(preg_match('/[\'"\;\-\-]/', $input)) { reject_input(); }
🧯 If You Can't Patch
- Isolate the system behind additional network segmentation and restrict access
- Implement multi-factor authentication for all staff accounts to reduce impact of credential theft
🔍 How to Verify
Check if Vulnerable:
Test the staff_login.php page with SQL injection payloads like ' OR '1'='1 in username/password fieldsCheck Version:
Check the software version in configuration files or about pagesVerify Fix Applied:
Attempt SQL injection tests and verify they are rejected or properly handled without database errors📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL syntax in parameters
- Database error messages containing SQL syntax in web logs
- Unusual database queries from web application user
Network Indicators:
- HTTP POST requests to staff_login.php containing SQL keywords
- Abnormal response patterns from login endpoint
SIEM Query:
source="web_logs" AND uri="/staff_login.php" AND (message="sql" OR message="syntax" OR message="union" OR message="select")
