🔍 How to Verify
Check if Vulnerable:
Check if REDAXO version is exactly 5.15.1 by looking at the version in the admin panel or checking the redaxo/src/core/version.php fileCheck Version:
grep -i 'version' /path/to/redaxo/src/core/version.phpVerify Fix Applied:
Verify the version has been updated to 5.15.2 or later in the admin panel or version.php file📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to modules.modules.php
- Suspicious file uploads or system command execution in web logs
- Unexpected process execution from web server user
Network Indicators:
- HTTP requests containing suspicious payloads targeting modules endpoint
- Outbound connections from web server to unknown IPs
SIEM Query:
source="web_logs" AND (uri="*modules.modules.php*" AND (method="POST" OR method="PUT")) AND (payload="*system(*" OR payload="*exec(*" OR payload="*shell_exec(*")
