📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access, data manipulation, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
SQL injection via GET parameter requires minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Consider implementing parameterized queries and input validation in the product.php file.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Input Validation Filter
allAdd input validation to sanitize the cid parameter before processing.
// PHP example: filter_var($_GET['cid'], FILTER_VALIDATE_INT);
🧯 If You Can't Patch
- Restrict access to /agms/product.php endpoint using network controls or authentication.
- Implement database user with minimal privileges to limit potential damage from SQL injection.
🔍 How to Verify
Check if Vulnerable:
Test the /agms/product.php?cid= parameter with SQL injection payloads like ' OR '1'='1.Check Version:
Check the software version in the application interface or configuration files.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or sanitized responses.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in web server logs for /agms/product.php requests
- Multiple failed database queries from single IP
Network Indicators:
- HTTP requests to /agms/product.php with SQL keywords in parameters
SIEM Query:
source="web_server" AND uri="/agms/product.php" AND (param="cid" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and)")
