CVE-2024-30384

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on EX4300 Series allows a locally authenticated attacker with low privileges to cause a Denial-of-Service (Dos). If a specific CLI command is issued, a PFE crash will occur. This will cause traffic forwarding to be interrupted until the system self-recovers. This issue affects Junos OS: All versions before 20.4R3-S10, 21.2 versions before 21.2R3-S7, 21.4 versions before 21.4R3-S6.

Summary		(es) Una verificación inadecuada de la vulnerabilidad de condiciones inusuales o excepcionales en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS en la serie EX4300 permite que un atacante autenticado localmente con privilegios bajos provoque una denegación de servicio (DOS). Si se emite un comando CLI específico, se producirá un bloqueo de PFE. Esto provocará que el reenvío de tráfico se interrumpa hasta que el sistema se recupere automáticamente. Este problema afecta a Junos OS: todas las versiones anteriores a 20.4R3-S10, versiones 21.2 anteriores a 21.2R3-S7, versiones 21.4 anteriores a 21.4R3-S6.
