Name of the Vulnerable Software and Affected Versions: Junos OS Evolved versions prior to 21.4R3-S4-EVO Junos OS Evolved versions 22.1-EVO prior to 22.1R3-S3-EVO Junos OS Evolved versions 22.2-EVO prior to 22.2R3-S2-EVO Junos OS Evolved versions 22.3-EVO prior to 22.3R2-S1-EVO, 22.3R3-EVO
Description: The issue is related to insufficient restriction of excessive authentication attempts, allowing a remote attacker to cause a limited Denial of Service (DoS) to the management plane. When an incoming connection is blocked due to exceeding the connections-per-second rate-limit, the system fails to consider existing connections for subsequent attempts, allowing the connection limit to be exceeded.
Recommendations: For Junos OS Evolved versions prior to 21.4R3-S4-EVO, update to version 21.4R3-S4-EVO or later. For Junos OS Evolved versions 22.1-EVO prior to 22.1R3-S3-EVO, update to version 22.1R3-S3-EVO or later. For Junos OS Evolved versions 22.2-EVO prior to 22.2R3-S2-EVO, update to version 22.2R3-S2-EVO or later. For Junos OS Evolved versions 22.3-EVO prior to 22.3R2-S1-EVO, 22.3R3-EVO, update to version 22.3R2-S1-EVO or 22.3R3-EVO or later.
