CVE-2024-30380

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-30380
An Improper Handling of Exceptional Conditions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause a Denial of Service (DoS), which causes the l2cpd process to crash by sending a specific TLV. The l2cpd process is responsible for layer 2 control protocols, such as STP, RSTP, MSTP, VSTP, ERP, and LLDP.  The impact of the l2cpd crash is reinitialization of STP protocols (RSTP, MSTP or VSTP), and MVRP and ERP, leading to a Denial of Service.  Continued receipt and processing of this specific TLV will create a sustained Denial of Service (DoS) condition. This issue affects: Junos OS: all versions before 20.4R3-S9, from 21.2 before 21.2R3-S7, from 21.3 before 21.3R3-S5, from 21.4 before 21.4R3-S4, from 22.1 before 22.1R3-S4, from 22.2 before 22.2R3-S2, from 22.3 before 22.3R2-S2, 22.3R3-S1, from 22.4 before 22.4R2-S2, 22.4R3, from 23.2 before 23.2R1-S1, 23.2R2; Junos OS Evolved: all versions before 21.2R3-S7, from 21.3 before 21.3R3-S5-EVO, from 21.4 before 21.4R3-S5-EVO, from 22.1 before 22.1R3-S4-EVO, from 22.2 before 22.2R3-S2-EVO, from 22.3 before 22.3R2-S2-EVO, 22.3R3-S1-EVO, from 22.4 before 22.4R2-S2-EVO, 22.4R3-EVO, from 23.2 before 23.2R1-S1-EVO, 23.2R2-EVO.

Summary
  • (es) Una vulnerabilidad de manejo inadecuado de condiciones excepcionales en Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS), lo que provoca que el proceso l2cpd se bloquee al enviar un TLV específico. El proceso l2cpd es responsable de los protocolos de control de capa 2, como STP, RSTP, MSTP, VSTP, ERP y LLDP. El impacto del fallo de l2cpd es la reinicialización de los protocolos STP (RSTP, MSTP o VSTP) y MVRP y ERP, lo que lleva a una denegación de servicio. La recepción y procesamiento continuo de este TLV específico creará una condición sostenida de Denegación de Servicio (DoS). Este problema afecta a: Junos OS: todas las versiones anteriores a 20.4R3-S9, desde 21.2 anteriores a 21.2R3-S7, desde 21.3 anteriores a 21.3R3-S5, desde 21.4 anteriores a 21.4R3-S4, desde 22.1 anteriores a 22.1R3-S4, desde 22.2 anteriores 22.2R3-S2, de 22.3 antes de 22.3R2-S2, 22.3R3-S1, de 22.4 antes de 22.4R2-S2, 22.4R3, de 23.2 antes de 23.2R1-S1, 23.2R2; Junos OS Evolved: todas las versiones anteriores a 21.2R3-S7, desde 21.3 anteriores a 21.3R3-S5-EVO, desde 21.4 anteriores a 21.4R3-S5-EVO, desde 22.1 anteriores a 22.1R3-S4-EVO, desde 22.2 anteriores a 22.2R3-S2- EVO, del 22.3 anterior a 22.3R2-S2-EVO, 22.3R3-S1-EVO, del 22.4 anterior a 22.4R2-S2-EVO, 22.4R3-EVO, del 23.2 anterior a 23.2R1-S1-EVO, 23.2R2-EVO.
