🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch is available. Consider upgrading to a newer version if released, or apply workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for the 'table' parameter to block SQL injection attempts.
Modify components/table_manager/html/edit_admin_table.php to use prepared statements or escape user inputs.
Web Application Firewall (WAF) Rules
allDeploy a WAF with rules to detect and block SQL injection patterns targeting the vulnerable endpoint.
Configure WAF to monitor and block requests to /components/table_manager/html/edit_admin_table.php with suspicious SQL characters.
🧯 If You Can't Patch
- Restrict access to the vulnerable component using network ACLs or authentication.
- Monitor logs for unusual database queries or access patterns to detect exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check if CuppaCMS version is V1.0 and review the edit_admin_table.php file for lack of input sanitization on the 'table' parameter.Check Version:
Check the CMS version in the admin panel or configuration files.Verify Fix Applied:
Test the vulnerable endpoint with SQL injection payloads; if blocked or sanitized, the fix is effective.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs, especially from the edit_admin_table.php endpoint.
Network Indicators:
- HTTP requests to edit_admin_table.php containing SQL keywords or special characters in the 'table' parameter.
SIEM Query:
Example: 'source="web_logs" AND uri="/components/table_manager/html/edit_admin_table.php" AND (param="table" AND value CONTAINS "' OR "--" OR "#")'
