🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement proper input validation and parameterized queries for the date_start parameter in /admin/calendar_of_events.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM events WHERE date_start = ?'); $stmt->bind_param('s', $date_start);
Web Application Firewall (WAF) Rules
allDeploy WAF rules to detect and block SQL injection attempts targeting the calendar_of_events.php endpoint
Configure WAF to block requests with SQL keywords in date_start parameter
🧯 If You Can't Patch
- Restrict access to /admin/calendar_of_events.php to only necessary users using network ACLs or authentication
- Implement database-level controls: use least privilege database accounts, enable logging of all database queries
🔍 How to Verify
Check if Vulnerable:
Test the /admin/calendar_of_events.php endpoint with SQL injection payloads in the date_start parameter (e.g., date_start=2025-01-01' OR '1'='1)Check Version:
Check system documentation or configuration files for version informationVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages or are properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web application, SQL syntax errors in application logs, multiple failed login attempts to admin interface
Network Indicators:
- HTTP requests to /admin/calendar_of_events.php with SQL keywords in parameters, unusual database connection patterns
SIEM Query:
source="web_logs" AND uri="/admin/calendar_of_events.php" AND (param="date_start" AND value MATCH "'.*OR.*|'.*AND.*|'.*UNION.*")
