Descriptions

A vulnerability in the HTTP client feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to read and modify data that should normally have been sent via an encrypted channel. The vulnerability is due to TCP port information not being considered when matching new requests to existing, persistent HTTP connections. An attacker could exploit this vulnerability by acting as a man-in-the-middle and then reading and/or modifying data that should normally have been sent through an encrypted channel.

Una vulnerabilidad en la funcionalidad HTTP client de los Software Cisco IOS y IOS XE, podría permitir a un atacante remoto no autenticado leer y modificar datos que normalmente deberían haber sido enviados por medio de un canal encriptado. La vulnerabilidad es debido a que no ha sido considerada la información del puerto TCP al hacer coincidir nuevas peticiones con conexiones HTTP persistentes y existentes. Un atacante podría explotar esta vulnerabilidad actuando como un intermediario y luego leyendo y/o modificando datos que normalmente deberían haberse enviado por medio de un canal encriptado.
