    Description:
    - The enterString API endpoint allows unauthenticated attackers to inject
    raw text into the target's active window without requiring keystroke
    simulation or special keycodes.
    - Works when "Allow unknown devices" setting is enabled (default: disabled)
    
    
    Vulnerable Component:
    - The /api/enterString endpoint with missing authentication checks
    
    
    # Identification:
    nmap -p- -T4 <TARGET_IP> --script ssl-cert
    Look for SSL cert with subject: CN=SecureHTTPServer/O=Evgeny Cherpak/C=US
