Description
An Improper Access Control vulnerability in the User Interface (UI) of Juniper Networks Junos OS allows a local, low-privileged attacker to bring down an interface, leading to a Denial-of-Service.
Users with "view" permissions can run a specific request interface command which allows the user to shut down the interface. This issue affects Junos OS:
* All versions before 21.2R3-S9, * from 21.4 before 21.4R3-S11, * from 22.2 before 22.2R3-S7, * from 22.4 before 22.4R3-S7, * from 23.2 before 23.2R2-S4, * from 23.4 before 23.4R2-S5, * from 24.2 before 24.2R2-S1, * from 24.4 before 24.4R1-S3, 24.4R2.
