CVSS: 7.2EPSS: 0%CPEs: 7EXPL: 0CVE-2020-1666 – Junos OS Evolved: 'console log-out-on-disconnect' fails to terminate session on console cable disconnection
https://notcve.org/view.php?id=CVE-2020-1666
The system console configuration option 'log-out-on-disconnect' In Juniper Networks Junos OS Evolved fails to log out an active CLI session when the console cable is disconnected. This could allow a malicious attacker with physical access to the console the ability to resume a previous interactive session and possibly gain administrative privileges. This issue affects all Juniper Networks Junos OS Evolved versions after 18.4R1-EVO, prior to 20.2R1-EVO. La opción de configuración de la consola del sistema "log-out-on-desconect" en Juniper Networks Junos OS Evolved presenta un fallo al cerrar la sesión de una sesión de la CLI activa cuando el cable de la consola está desconectado. Esto podría permitir a un atacante malicioso con acceso físico a la consola la capacidad de reanudar una sesión interactiva anterior y posiblemente conseguir privilegios administrativos. • https://kb.juniper.net/JSA11063 • CWE-284: Improper Access Control CWE-613: Insufficient Session Expiration •
