Name of the Vulnerable Software and Affected Versions Junos OS Evolved versions 22.3-EVO before 22.3R2-EVO Junos OS Evolved versions 22.4-EVO before 22.4R1-S1-EVO, 22.4R2-EVO
Description An Improper Neutralization of Special Elements issue 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 does not properly handle command options in some cases, allowing users to execute specific CLI commands with a crafted set of parameters to escalate their privileges to root on shell level.
Recommendations For Junos OS Evolved versions 22.3-EVO before 22.3R2-EVO, update to version 22.3R2-EVO or later. For Junos OS Evolved versions 22.4-EVO before 22.4R1-S1-EVO, update to version 22.4R1-S1-EVO or later. For Junos OS Evolved versions 22.4-EVO before 22.4R2-EVO, update to version 22.4R2-EVO or later. As a temporary workaround, consider restricting the use of the vulnerable CLI commands until a patch is available.
