Technical description

A Missing Authorization vulnerability in the internal virtual routing and forwarding (VRF) of Juniper Networks Junos OS Evolved allows a local, low-privileged user to gain root privileges, leading to a system compromise.

* All versions before 22.2R3-S7-EVO, 

* from 22.4 before 22.4R3-S7-EVO, 

* from 23.2 before 23.2R2-S4-EVO, 

* from 23.4 before 23.4R2-S5-EVO, 

* from 24.2 before 24.2R2-S1-EVO
