Description
An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the CLI of Juniper Networks Junos OS and Junos OS Evolved allows a high privileged, local attacker to escalated their privileges to root. When a user provides specifically crafted arguments to the 'request system logout' command, these will be executed as root on the shell, which can completely compromise the device. This issue affects: Junos OS: * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S8, * 22.2 versions before 22.2R3-S6, * 22.3 versions before 22.3R3-S3, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S1, * 23.4 versions before 23.4R1-S2, 23.4R2; Junos OS Evolved: * all versions before 22.4R3-S6-EVO, * 23.2-EVO versions before 23.2R2-S1-EVO, * 23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO.
