🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to ensure ID parameter contains only numeric values
In ajax.php, add: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }
Web Application Firewall Rule
allBlock SQL injection patterns targeting the delete_package endpoint
WAF rule: Block requests to /ajax.php?action=delete_package containing SQL keywords in ID parameter
🧯 If You Can't Patch
- Block external access to /ajax.php endpoint at network firewall level
- Implement strict database user permissions with read-only access where possible
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /ajax.php?action=delete_package&ID=1' OR '1'='1Check Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and return error or sanitized response📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /ajax.php?action=delete_package with unusual ID parameters
- Database error logs showing SQL syntax errors
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, INSERT) in URL parameters
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND url="/ajax.php" AND url_query="*action=delete_package*" AND (url_query="*'*" OR url_query="*UNION*" OR url_query="*SELECT*")
