🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement workarounds or consider replacing the software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameter validation to filter SQL injection attempts in the q parameter
Modify /accomodation.php to add: $q = mysqli_real_escape_string($connection, $_GET['q']);
Web Application Firewall
allDeploy WAF with SQL injection rules to block exploitation attempts
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the vulnerable application
🔍 How to Verify
Check if Vulnerable:
Test /accomodation.php?q=1' OR '1'='1 and observe if SQL error or unexpected behavior occursCheck Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Test with same payload after implementing fixes - should return proper error or no data📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple rapid requests to /accomodation.php with SQL-like parameters
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in q parameter
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND uri="/accomodation.php" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR '1'='1*")
