A Missing Authorization vulnerability in the CLI of Juniper Networks Junos OS on EX Series allows a local, authenticated attacker to cause a Denial-of-Service (DoS).

On EX2300, EX4000, EX4100, EX4300-MP (Multigigabit) and EX4400 switches, an authenticated, local attacker with no specific permissions or class can execute a specific, privileged CLI 'request' command which will cause complete traffic impact until the system automatically recovers.

This issue affects Junos OS on EX2300, EX4000, EX4100, EX4300-MP (Multigigabit) and EX4400:

• 23.2R2 versions before 23.2R2-S6,
• 23.4 versions before 23.4R2-S8,
• 24.2 versions before 24.2R2-S4,
• 24.4 versions before 24.4R2-S3,
• 25.2 versions before 25.2R2,
• 25.4 versions before 25.4R1-S1.
