Summary
A vulnerability in the implementation of Point-to-Point Tunneling Protocol (PPTP) functionality in Cisco Aironet 1810, 1830, and 1850 Series Access Points could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Generic Routing Encapsulation (GRE) frames that pass through the data plane of an affected access point. An attacker could exploit this vulnerability by initiating a PPTP connection to an affected access point from a device that is registered to the same wireless network as the access point and sending a malicious GRE frame through the data plane of the access point. A successful exploit could allow the attacker to cause the NSS core process on the affected access point to crash, which would cause the access point to reload and result in a DoS condition. This vulnerability affects Cisco Aironet 1810, 1830, and 1850 Series Access Points that are running Cisco Mobility Express Software Release 8.4.100.0, 8.5.103.0, or 8.5.105.0 and are configured as a master, subordinate, or standalone access point. Cisco Bug IDs: CSCvf73890.

"value": "Una vulnerabilidad en la implementaci\u00f3n de la funcionalidad PPTP (Point-to-Point Tunneling Protocol) en los puntos de acceso de las series 1810, 1830 y 1850 de Cisco Aironet podr\u00eda permitir que un atacante remoto no autenticado provocara el reinicio de un dispositivo afectado, lo que provocar\u00eda una condici\u00f3n de denegaci\u00f3n de servicio (DoS). La vulnerabilidad se debe a la validaci\u00f3n insuficiente de las tramas GRE (Generic Routing Encapsulation) que pasan a trav\u00e9s del plano de datos de un punto de acceso afectado. Un atacante podr\u00eda explotar esta vulnerabilidad iniciando una conexi\u00f3n PPTP a un punto de acceso afectado desde un dispositivo registrado en la misma red inal\u00e1mbrica que el punto de acceso y enviando un marco GRE malicioso a trav\u00e9s del plano de datos del punto de acceso. Su explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante causar que el proceso del n\u00facleo NSS en el punto de acceso afectado se bloquee, lo que causar\u00eda que el punto de acceso se reinicie y una condici\u00f3n de denegaci\u00f3n de servicio. Esta vulnerabilidad afecta a los puntos de acceso de las series 1810, 1830 y 1850 de Cisco Aironet que ejecuten las versiones de software 8.4.100.0, 8.5.103.0 o 8.5.105.0 de Cisco Mobility Express y que est\u00e9n configurados como puntos de acceso maestro, subordinado o independiente.
