{"id":"CVE-2022-22237","state":"PUBLISHED","title":"Junos OS: Peers not configured for TCP-AO can establish a BGP or LDP session even if authentication is configured locally","description":"An Improper Authentication vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause an impact on confidentiality or integrity. A vulnerability in the processing of TCP-AO will allow a BGP or LDP peer not configured with authentication to establish a session even if the peer is locally configured to use authentication. This could lead to untrusted or unauthorized sessions being established.
