Descriptions

Askey AP5100W devices through AP5100W_Dual_SIG_1.01.097 are affected by WPS PIN offline brute-force cracking. This arises because of issues with the random number selection for the Diffie-Hellman exchange. By capturing an attempted (and even failed) WPS authentication attempt, it is possible to brute force the overall authentication exchange. This allows an attacker to obtain the recovered WPS PIN in minutes or even seconds, and eventually obtain the Wi-Fi PSK key, gaining access to the Wi=Fi network.

Los dispositivos Askey AP5100W versiones hasta AP5100W_Dual_SIG_1.01.097 están afectados por un descifrado de fuerza bruta fuera de línea WPS PIN. Esto surge debido a problemas con la selección de números aleatorios para el intercambio Diffie-Hellman. Al capturar un intento de autenticación WPS intentado (e incluso fallido), es posible forzar el intercambio de autenticación general por fuerza bruta. Esto permite a un atacante obtener el WPS PIN recuperado en minutos o incluso segundos y, eventualmente, obtener la clave Wi-Fi PSK, consiguiendo acceso a la red Wi=Fi
