📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the POS database including theft of payment card data, customer information, and business records, potentially leading to data destruction and business disruption.
Likely Case
Unauthorized access to sensitive restaurant data including menu items, pricing, customer information, and potentially payment data if stored in the same database.
If Mitigated
Limited impact with proper network segmentation, database permissions, and input validation controls in place.
🎯 Exploit Status
The vulnerability is in a REST API endpoint and requires no authentication, making exploitation straightforward with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://aptsys.com
Restart Required: No
Instructions:
1. Contact Aptsys for patch availability 2. Apply any available security updates 3. Test the fix in a non-production environment 4. Deploy to production systems
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to restrict the id parameter to numeric values only
Implement regex validation: ^[0-9]+$ for the id parameter
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Configure WAF to block requests containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Implement network segmentation to isolate the POS backend from untrusted networks
- Deploy database activity monitoring to detect and alert on suspicious SQL queries
🔍 How to Verify
Check if Vulnerable:
Test the GetServiceByRestaurantID endpoint with SQL injection payloads like: /api/GetServiceByRestaurantID?id=1' OR '1'='1Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Test with the same payloads after remediation - should receive error or no data leakage📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed requests to GetServiceByRestaurantID endpoint
- Requests with SQL keywords in id parameter
Network Indicators:
- Unusual database query patterns from application server
- High volume of requests to the vulnerable endpoint
SIEM Query:
source="application.log" AND ("GetServiceByRestaurantID" AND ("UNION" OR "SELECT" OR "OR 1=1" OR "'--"))
