🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify teacher_login.php to use prepared statements and validate username input
Replace vulnerable SQL queries with parameterized queries using PDO or mysqli prepared statements
Web Application Firewall Rules
allImplement WAF rules to block SQL injection patterns
Add WAF rule: deny requests containing SQL keywords like UNION, SELECT, INSERT, DELETE in username parameter
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Test the /smsa/teacher_login.php endpoint with SQL injection payloads in username parameter (e.g., admin' OR '1'='1)Check Version:
Check PHP source files for version information or review project documentationVerify Fix Applied:
Attempt SQL injection after implementing parameterized queries and verify requests are blocked or sanitized📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL syntax in username field
- Unusual database queries from web application user
Network Indicators:
- HTTP POST requests to /smsa/teacher_login.php containing SQL keywords
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="/smsa/teacher_login.php" AND (username="*UNION*" OR username="*SELECT*" OR username="*OR*'1'='1*")
