An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on EX4300 Series allows a locally authenticated attacker with low privileges to cause aย Denial-of-Service (Dos).
If a specific CLIย command is issued, aย PFE crash will occur. This will cause traffic forwarding to be interrupted until the system self-recovers.
This issue affects Junos OS:
All versions before 20.4R3-S10,
21.2 versions before 21.2R3-S7,
21.4 versions before 21.4R3-S6.
