CVE-2024-30403

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-30403
A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). When Layer 2 traffic is sent through a logical interface, MAC learning happens. If during this process, the interface flaps, an Advanced Forwarding Toolkit manager (evo-aftmand-bt) core is observed. This leads to a PFE restart. The crash reoccurs if the same sequence of events happens, which will lead to a sustained DoS condition. This issue affects Juniper Networks Junos OS Evolved 23.2-EVO versions earlier than 23.2R1-S1-EVO, 23.2R2-EVO.

Summary
  • (es) Una vulnerabilidad de desreferencia de puntero NULL en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Cuando el tráfico de Capa 2 se envía a través de una interfaz lógica, se produce el aprendizaje de MAC. Si durante este proceso, la interfaz parpadea, se observa un núcleo del administrador Advanced Forwarding Toolkit (evo-aftmand-bt). Esto conduce a un reinicio de PFE. El bloqueo vuelve a ocurrir si ocurre la misma secuencia de eventos, lo que conducirá a una condición DoS sostenida. Este problema afecta a Juniper Networks Junos OS Evolved: versiones 23.2-EVO anteriores a 23.2R1-S1-EVO, 23.2R2-EVO.
