Descriptions

An Incorrect Comparison vulnerability in the local address verification API of Juniper Networks Junos OS Evolved allows an unauthenticated network-adjacent attacker to create sessions or send traffic to the device using the network and broadcast address of the subnet assigned to an interface. This is unintended and unexpected behavior and can allow an attacker to bypass certain compensating controls, such as stateless firewall filters.

* All versions before 21.4R3-S8-EVO,
* 22.2-EVO before 22.2R3-S4-EVO,
