Title
Junos OS Evolved: CLI parameter processing issue allows privilege escalation
Summary
An Improper Neutralization of Special Elements vulnerability in Juniper Networks Junos OS Evolved commands allows a local, authenticated attacker with low privileges to escalate their privileges to 'root' leading to a full compromise of the system. The Junos OS Evolved CLI doesn't properly handle command options in some cases, allowing users which execute specific CLI commands with a crafted set of parameters to escalate their privileges to root on shell level. This issue affects Junos OS Evolved: * 22.3-EVO versions before 22.3R2-EVO, * 22.4-EVO versions before 22.4R1-S1-EVO, 22.4R2-EVO.
