-Hardening and detection:
-
-- Reject inputs that start with `-` and enforce strict allowlists and types (IP, MAC, SSID, etc.).
-- Always pass user data after a literal `--` where supported and never allow extra flags from user-controlled fields.
-- Prefer safe APIs (no shell); for wrappers, construct fixed argv templates with no user-controlled flags.
-- Look for unauthenticated hits to centralized CGI endpoints (e.g., `/cgi-bin/cstecgi.cgi`) with selector parameters and values beginning with `-`.
