Instructions for AP8021 and AP8022 Series Devices:

AP8021 and AP8022 Series devices are vulnerable to CVE-2022-22177 when configured for both the IPv4 unicast routing protocol and the IPv6 unicast routing protocol. To mitigate this issue, configure these devices to only use one of the two protocols.

To mitigate this issue, configure a Junos OS system as follows:

# set interfaces ge-0/0/0 unit 0 family inet address dhcp;
# set interfaces ge-0/0/1 unit 0 family inet address dhcp;
# set interfaces ge-1/1/1 unit 0 family inet address dhcp;
# set protocols ospfv3 area 0.0.10.10 { interface ge-0/0/2.2 { } interface ge-1/1/1.3 { } }
