⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the database including data theft, data destruction, and potential remote code execution if database permissions allow.
Likely Case
Unauthorized access to sensitive real estate data, client information, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries in place.
🎯 Exploit Status
Public proof-of-concept available showing SQL injection via the delete_estate parameter.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for the delete_estate parameter to only accept expected values.
Modify /reps/classes/Master.php to validate and sanitize user input before SQL execution
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the vulnerable endpoint.
Add WAF rule: Block requests to /reps/classes/Master.php?f=delete_estate with SQL injection patterns
🧯 If You Can't Patch
- Disable or restrict access to /reps/classes/Master.php endpoint
- Implement network segmentation to isolate the vulnerable system
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /reps/classes/Master.php?f=delete_estate&id=1' OR '1'='1
Check Version:
Check application version in configuration files or about pages
Verify Fix Applied:
Test with same payloads after implementing fixes - should return error or no SQL execution
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple requests to Master.php with SQL patterns
- Failed authentication attempts followed by SQL injection attempts
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) targeting the vulnerable endpoint
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND uri="/reps/classes/Master.php" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR*1=1*")
