Descriptions
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:
* All versions before 21.4R3-S4-EVO,
* 22.1-EVO versions before 22.1R3-S3-EVO,
* 22.2-EVO versions before 22.2R3-S2-EVO,
* 22.3-EVO versions before 22.3R2-S1-EVO, 22.3R3-EVO.
Una vulnerabilidad de restricción inadecuada de intentos de autenticación excesivos en Juniper Networks Junos OS Evolved permite que un atacante basado en red no autenticado cause una denegación de servicio (DoS) limitada en el plano de administración. Cuando se bloquea una conexión entrante porque excedió el límite de velocidad de conexiones por segundo, el sistema ya no considera las conexiones existentes para intentos de conexión posteriores, de modo que se pueda exceder el límite de conexión. Este problema afecta a Junos OS Evolved: todas las versiones anteriores a 21.4R3-S4-EVO, versiones 22.1-EVO anteriores a 22.1R3-S3-EVO, versiones 22.2-EVO anteriores a 22.2R3-S2-EVO, versiones 22.3-EVO anteriores a 22.3R2-S1 -EVO, 22.3R3-EVO.
