Descriptions

A vulnerability in the authentication and authorization checking mechanisms of Cisco Wireless LAN Controller (WLC) Software could allow an authenticated, adjacent attacker to gain network access to a Cisco TrustSec domain. Under normal circumstances, this access should be prohibited. The vulnerability is due to the dynamic assignment of Security Group Tags (SGTs) during a wireless roam from one Service Set Identifier (SSID) to another within the Cisco TrustSec domain. An attacker could exploit this vulnerability by attempting to acquire an SGT from other SSIDs within the domain. Successful exploitation could allow the attacker to gain privileged network access that should be prohibited under normal circumstances.

Una vulnerabilidad en los mecanismos de comprobación de autenticación y autorización de Cisco Wireless LAN Controller (WLC) Software podría permitir que un atacante autenticado adyacente obtenga acceso de red a un dominio Cisco TrustSec. En circunstancias normales, el acceso debería estar prohibido. La vulnerabilidad se debe a la asignación dinámica de STG (Security Group Tags) durante un roam inalámbrico de un SSID (Service Set Identifier) a otro en el dominio Cisco TrustSec. Un atacante podría explotar esta vulnerabilidad intentando adquirir un SGT de otros SSID en el dominio. Su explotación con éxito podría permitir que el atacante obtenga privilegios de red que deberían estar prohibidos en otras circunstancias.
