🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize the 'searchfor' parameter before processing SQL queries.
Modify /eris/index.php to include parameter validation using prepared statements or whitelisting.
Web Application Firewall Rule
allBlock SQL injection patterns in the 'searchfor' parameter.
Add WAF rule: deny requests containing SQL keywords like UNION, SELECT, INSERT in the searchfor parameter.
🧯 If You Can't Patch
- Disable the vulnerable endpoint /eris/index.php?q=result&searchfor=advancesearch if not required.
- Implement network segmentation to isolate the vulnerable system from sensitive data stores.
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads like: /eris/index.php?q=result&searchfor=advancesearch' OR '1'='1Check Version:
Check application version in admin panel or configuration files; look for 'v1.0' in source code.Verify Fix Applied:
Retest with SQL injection payloads after implementing fixes; ensure no database errors or unexpected results.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests with SQL keywords in searchfor parameter
Network Indicators:
- HTTP requests to /eris/index.php containing SQL injection patterns in parameters
SIEM Query:
source="web_logs" AND uri="/eris/index.php" AND (param="searchfor" AND value MATCHES "(?i)(union|select|insert|delete|--|')")
