🔍 How to Verify
Check if Vulnerable:
Check the QR Menü version in the application interface or configuration files. If version is between s1.05.05 and v1.05.12 (exclusive), the system is vulnerable.Check Version:
Check application admin panel or configuration files for version information.Verify Fix Applied:
After patching, verify the version shows v1.05.12 or higher in the application interface.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP request patterns with crafted headers
- Multiple requests with similar payloads attempting to manipulate responses
- Unexpected HTTP response headers in logs
Network Indicators:
- HTTP requests containing CRLF injection sequences
- Multiple similar requests to the same endpoint with varying headers
- Unexpected HTTP response splitting in traffic
SIEM Query:
source="qr_menu_logs" AND (http_request CONTAINS "%0D%0A" OR http_request CONTAINS "%0A" OR http_request CONTAINS "\r\n")
