🔍 How to Verify
Check if Vulnerable:
Check if your SimplCommerce code includes commit 230310c8d7a0408569b292c5a805c459d47a1d8f or earlierCheck Version:
git log --oneline | grep 230310c8d7a0408569b292c5a805c459d47a1d8fVerify Fix Applied:
Verify the latest code does not contain the vulnerable commit and test quantity parameter validation📡 Detection & Monitoring
Log Indicators:
- Unusually large quantity values in cart requests
- Application crashes or memory errors in logs
Network Indicators:
- HTTP POST requests to cart endpoints with abnormal quantity parameters
SIEM Query:
source="web_logs" AND uri="/cart/add" AND quantity>1000
