Published 2024-07-11
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: All versions before 20.4R3-S7-EVO, 21.2-EVO versions before 21.2R3-S8-EVO, 21.4-EVO versions before 21.4R3-S7-EVO, 22.2-EVO versions before 22.2R3-EVO, 22.3-EVO versions before 22.3R2-EVO, 22.4-EVO versions before 22.4R2-EVO.
