Title
Junos OS Evolved: ACX 7000 Series: Multicast traffic is looped in a multihoming EVPN MPLS scenario
Summary
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated, adjacent attacker to cause a
Denial-of-Service (DoS).
On all ACX 7000 Series platforms running
Junos OS Evolved, and configured with IRBs, if a Customer Edge device (CE) device is dual homed to two Provider Edge devices (PE) a traffic loop will occur when the CE sends multicast packets. This issue can be triggered by IPv4 and IPv6 traffic.
This issue affects Junos OS Evolved:
All versions from 22.2R1-EVO and later versions before 22.4R2-EVO,
This issue does not affect Junos OS Evolved versions before 22.1R1-EVO.
