🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.0.25 or later
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Backup your database and configuration. 2. Download and install Simple POS version 4.0.25 or later. 3. Restart the Simple POS service. 4. Verify the fix by testing the vulnerable endpoint.
🔧 Temporary Workarounds
Input Validation Filter
allImplement input validation to sanitize the columns[0][search][value] parameter
Modify the products/get_products/ endpoint code to validate and sanitize all user inputs
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule to block patterns like UNION SELECT, OR 1=1, --, ;, etc.
🧯 If You Can't Patch
- Isolate the Simple POS system from the internet and restrict access to trusted IP addresses only
- Implement strict database permissions and use parameterized queries in custom code modifications
🔍 How to Verify
Check if Vulnerable:
Test the products/get_products/ endpoint with SQL injection payloads in the columns[0][search][value] parameterCheck Version:
Check Simple POS version in admin panel or configuration filesVerify Fix Applied:
Attempt the same SQL injection tests after patching - they should be blocked or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts followed by SQL injection patterns
- Database error messages containing SQL syntax
Network Indicators:
- HTTP requests to products/get_products/ with SQL keywords in parameters
- Unusual database connection patterns from application server
SIEM Query:
