allImplement WAF rules to block path traversal patterns in file_name parameter
🧯 If You Can't Patch
- Isolate affected devices in separate network segments with strict access controls
- Implement monitoring and alerting for suspicious file access patterns
🔍 How to Verify
Check if Vulnerable:
Test if you can access files outside intended directory by manipulating file_name parameter in ?g=log_export_file requestsCheck Version:
Check device web interface or CLI for firmware version informationVerify Fix Applied:
Verify that path traversal attempts are blocked and return appropriate error responses📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns in web logs
- Multiple failed attempts with ../ patterns in file_name parameter
Network Indicators:
- HTTP requests to ?g=log_export_file with suspicious file_name parameters containing ../ patterns
SIEM Query:
web.url:*log_export_file* AND web.param.file_name:*../*
