The vulnerability exists because the Cisco Mobility Express controller of the affected software configures the default SSH user account for an access point to be the first SSH user account that was created for the Mobility Express controller, if an administrator added user accounts directly to the controller instead of using the default configuration or the SSH username creation wizard. Although the user account has read-only privileges for the Mobility Express controller, the account could have administrative privileges for an associated access point. An attacker who has valid user credentials for an affected controller could exploit this vulnerability by using the default SSH user account to authenticate to an affected access point via SSH. A successful exploit could allow the attacker to log in to the affected access point with administrative privileges and perform arbitrary administrative actions. This vulnerability affects the following Cisco products: Aironet 1800 Series Access Points that are running Cisco Mobility Express Software Releases 8.2.121.0 through 8.5.105.0, Aironet 2800 Series Access Points that are running Cisco Mobility Express Software Releases 8.3.102.0 through 8.5.105.0, Aironet 3800 Series Access Points that are running Cisco Mobility Express Software Releases 8.3.102.0 through 8.5.105.0.

Esta vulnerabilidad existe porque el controlador de Cisco Mobility Express del software afectado configura la cuenta de usuario SSH para un punto de acceso para que sea la primera cuenta de usuario SSH en crearse para el controlador Mobility Express, si un administrador a\u00f1ade cuentas de usuario directamente al controlador en vez de utilizar la configuraci\u00f3n por defecto o el asistente de creaci\u00f3n de nombres de usuario SSH. Aunque la cuenta de usuario tiene privilegios de solo lectura para el controlador Mobility Express, la cuenta podr\u00eda tener privilegios de administraci\u00f3n para un punto de acceso. Un atacante que tenga credenciales de usuario v\u00e1lidas para un controlador afectado podr\u00eda explotar esta vulnerabilidad utilizando la cuenta de usuario SSH por defecto para autenticarse en un punto de acceso afectado mediante SSH. Un exploit con \u00e9xito podr\u00eda permitir que el atacante consiga iniciar sesi\u00f3n en el punto de acceso afectado con privilegios administrativos y realizar acciones administrativas arbitrarias.
