Check if running HuankeMao SCRM version 0.0.3 or earlier and examine WxkConfig.php for unrestricted file upload validation.Check Version:
Check software documentation or configuration files for version informationVerify Fix Applied:
Test file upload functionality with various file types to ensure only allowed extensions are accepted.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to administrator backend
- Multiple failed upload attempts
- Uploads of executable files like .php, .jsp, .asp
Network Indicators:
- HTTP POST requests to upload_domain_verification_file endpoint with unusual file types
- Traffic patterns suggesting web shell communication
SIEM Query:
source="web_server" AND (uri="*upload_domain_verification_file*" OR file_extension IN ("php", "jsp", "asp", "exe"))
