🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with secure alternative.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to only accept numeric values for ID parameter
Modify /admin/delete_s5.php to validate ID parameter as integer before processing
Parameterized Query Implementation
allReplace dynamic SQL with prepared statements
Rewrite SQL queries in delete_s5.php to use parameterized queries
🧯 If You Can't Patch
- Block access to /admin/delete_s5.php at web server or firewall level
- Implement WAF rules to detect and block SQL injection patterns
🔍 How to Verify
Check if Vulnerable:
Test /admin/delete_s5.php with SQL injection payloads like ' OR '1'='1 in ID parameterCheck Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with same payloads and verify they are rejected or properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple failed delete attempts with malformed ID parameters
- Access to delete_s5.php with non-numeric ID values
Network Indicators:
- HTTP requests to /admin/delete_s5.php with SQL keywords in parameters
- Unusual database query patterns from web server
SIEM Query:
source="web_server" AND uri="/admin/delete_s5.php" AND (param="ID" AND value MATCH "'.*'|OR|UNION|SELECT")
