Descriptions

A partial authentication bypass vulnerability exists on Atheros AR9132 3.60(AMX.8), AR9283 1.85, and AR9285 1.0.0.12NA devices. The vulnerability allows sending an unencrypted data frame to a WPA2-protected WLAN router where the packet is routed through the network. If successful, a response is sent back as an encrypted frame, which would allow an attacker to discern information or potentially modify data.

Se presenta una vulnerabilidad de omisión de autenticación parcial en los dispositivos Atheros AR9132 versión 3.60(AMX.8), AR9283 versión 1.85 y AR9285 versión 1.0.0.12NA. La vulnerabilidad permite enviar una trama de datos no cifrada hacia un enrutador WLAN protegido por WPA2 donde el paquete se enruta por medio de la red. Si tiene éxito, es enviada una respuesta como una trama cifrada, lo que permitiría a un atacante discernir información o potencialmente modificar datos
