Descriptions

TP-Link Omada SDN Software Controller before 5.0.15 does not check if the authentication method specified in a connection request is allowed. An attacker can bypass the captive portal authentication process by using the downgraded "no authentication" method, and access the protected network. For example, the attacker can simply set window.authType=0 in client-side JavaScript.

TP-Link Omada SDN Software Controller versiones anteriores a 5.0.15, no comprueba si el método de autenticación especificado en una petición de conexión está permitido. Un atacante puede omitir el proceso de autenticación del portal cautivo al usar el método "no authentication" degradado, y acceder a la red protegida. Por ejemplo, el atacante puede simplemente establecer window.authType=0 en el JavaScript del lado del cliente
