TITLE

Juniper Networks Junos OS Evolved  Session deadline vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2020-012196

DESCRIPTION

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. The operating system provides a secure programming interface and Junos SDK. Junos OS Evolved is an upgraded version of Junos OS. A security vulnerability exists in Junos OS Evolved that could allow an attacker to bypass restrictions by ignoring logoff-disconnect in order to escalate his privileges
