Wavlink WL-WN530BE1-A firmware through M30BE1 V251117 contains an OS command injection vulnerability in the sub 23B54 function of the ioos binary, which passes the unsanitized file id parameter of /protocol.csp?opt=ovpn file requests with type=del to popen(). A remote unauthenticated attacker can send a forged IP-FROM: 127.0.0.1 header to bypass login and execute arbitrary commands as root.
