CVE-2024-21590

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-21590
An Improper Input Validation vulnerability in Juniper Tunnel Driver (jtd) and ICMP module of Juniper Networks Junos OS Evolved allows an unauthenticated attacker within the MPLS administrative domain to send specifically crafted packets to the Routing Engine (RE) to cause a Denial of Service (DoS).  When specifically crafted transit MPLS IPv4 packets are received by the Packet Forwarding Engine (PFE), these packets are internally forwarded to the RE. Continued receipt of these packets may create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: * All versions before 21.2R3-S8-EVO; * from 21.4-EVO before 21.4R3-S6-EVO; * from 22.2-EVO before 22.2R3-S4-EVO; * from 22.3-EVO before 22.3R3-S3-EVO; * from 22.4-EVO before 22.4R3-EVO; * from 23.2-EVO before 23.2R2-EVO. * from 23.4-EVO before 23.4R1-S1-EVO.

Summary
  • (es) Una vulnerabilidad de validación de entrada incorrecta en Juniper Tunnel Driver (jtd) y el módulo ICMP de Juniper Networks Junos OS Evolved permite a un atacante no autenticado dentro del dominio administrativo MPLS enviar paquetes específicamente manipulados al motor de enrutamiento (RE) para provocar una denegación de servicio (DoS). ). Cuando el motor de reenvío de paquetes (PFE) recibe paquetes MPLS IPv4 de tránsito específicamente manipulados, estos paquetes se reenvían internamente al RE. La recepción continua de estos paquetes puede crear una condición sostenida de Denegación de Servicio (DoS). Este problema afecta a Juniper Networks Junos OS: * Todas las versiones anteriores a 21.2R3-S8-EVO; * desde 21.4-EVO antes de 21.4R3-S6-EVO; * de 22.2-EVO antes de 22.2R3-S4-EVO; *de 22.3-EVO antes de 22.3R3-S3-EVO; * de 22.4-EVO antes de 22.4R3-EVO; *desde 23.2-EVO antes 23.2R2-EVO. *desde 23.4-EVO antes 23.4R1-S1-EVO.
