CVE-2024-21607 is a vulnerability that affects Juniper Networks Junos OS on MX Series and EX9200 Series. It is an unsupported feature in the UI vulnerability that allows an unauthenticated, network-based attacker to cause partial impact to the integrity of the device. This vulnerability occurs when the "tcp-reset" option is added to the "reject" action in an IPv6 filter, causing packets to be permitted instead of rejected. The issue can be remediated by treating the payload-protocol match the same as a "next-header" match. It is important to note that this vulnerability does not affect IPv4 firewall filters. The potential danger posed by this vulnerability includes a medium base severity rating, with a base score of 5.3 and an impact score of 1.4.
