📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, authentication bypass, and potential server takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized access to sensitive customer data (personal information, payment details), service manipulation, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.
🎯 Exploit Status

🛠️ 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
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Input Validation Filter
allImplement server-side input validation to sanitize parameters before processing.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in the application code
- Restrict database user permissions to minimum required access
🔍 How to Verify
Check if Vulnerable:
Test the endpoint /ocwbs/classes/Master.php?f=get_vehicle_service with SQL injection payloads using tools like sqlmap or manual testing.Check Version:
Check application version in admin panel or configuration files.Verify Fix Applied:
Retest the vulnerable endpoint with SQL injection payloads to confirm they are properly rejected or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter manipulation attempts
- Requests with SQL keywords in parameters
