Descriptions

The SSH implementation in Cisco StarOS before 19.3.M0.62771 and 20.x before 20.0.M0.62768 on ASR 5000 devices mishandles a multi-user public-key authentication configuration, which allows remote authenticated users to gain privileges by establishing a connection from an endpoint that was previously used for an administrator's connection, aka Bug ID CSCux22492.

La implementación de SSH en Cisco StarOS en versiones anteriores a 19.3.M0.62771 y 20.x en versiones anteriores a 20.0.M0.62768 en dispositivos ASR 5000 no maneja correctamente una configuración de autenticación de clave pública multi usuario, lo que permite a usuarios remotos autenticados obtener privilegios estableciendo una conexión desde un dispositivo final que fue previamente utilizado para la conexión de un administrador, también conocida como Bug ID CSCux22492.
