An Improper Restriction of Excessive Authentication Attempts vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a limited Denial of Service (DoS) to the management plane.
When an incoming connection was blocked because it exceeded the connections-per-second rate-limit, the system doesn’t consider existing connections anymore for subsequent connection attempts so that the connection limit can be exceeded.
This issue affects Junos OS Evolved:
