Descriptions
A vulnerability in Cisco Aironet 1830 Series and Cisco Aironet 1850 Series Access Points running Cisco Mobility Express Software could allow an unauthenticated, remote attacker to take complete control of an affected device. The vulnerability is due to the existence of default credentials for an affected device that is running Cisco Mobility Express Software, regardless of whether the device is configured as a master, subordinate, or standalone access point. An attacker who has layer 3 connectivity to an affected device could use Secure Shell (SSH) to log in to the device with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco Aironet 1830 Series and Cisco Aironet 1850 Series Access Points that are running an 8.2.x release of Cisco Mobility Express Software prior to Release 8.2.111.0, regardless of whether the device is configured as a master, subordinate, or standalone access point. Release 8.2 was the first release of Cisco Mobility Express Software for next generation Cisco Aironet Access Points. Cisco Bug IDs: CSCva50691.
Una vulnerabilidad en Cisco Aironet 1830 Series y Cisco Aironet 1850 Series Access Points running Cisco Mobility Express Software podría permitir a un atacante remoto no autenticado tomar el control completo de un dispositivo afectado. La vulnerabilidad se debe a la existencia de credenciales predeterminadas para un dispositivo afectado que ejecuta el software Cisco Mobility Express, independientemente de si el dispositivo está configurado como punto de acceso maestro, subordinado o independiente. Un atacante que tenga una conectividad de capa 3 con un dispositivo afectado podría usar Secure Shell (SSH) para iniciar sesión en el dispositivo con privilegios elevados. Una explotación exitosa podría permitir al atacante tomar el control completo del dispositivo. Esta vulnerabilidad afecta a Cisco Aironet 1830 Series y Cisco Aironet 1850 Series Access Points que están ejecutando un lanzamiento de 8.2.x Cisco Mobility Express Software anterior a la versión lanzamiento 8.2.111.0, independientemente de si el dispositivo está configurado como un punto de acceso maestro, subordinado o independiente. El lanzamiento 8.2 fue el primer lanzamiento de Cisco Mobility Express Software para la proxima generación Cisco Aironet Access Points. Cisco Bug IDs: CSCva50691.
