juniper·CWE-1285·Published 2022-10-18
An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). On SRX5000 Series with SPC3, SRX4000 Series, and vSRX, when PowerMode IPsec is configured and a malformed ESP packet matching an established IPsec tunnel is received the PFE crashes. This issue affects Juniper Networks Junos OS on SRX5000 Series with SPC3, SRX4000 Series, and vSRX: All versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2.

Una vulnerabilidad de comprobación inapropiada del índice, la posición o el desplazamiento especificados en la entrada en Packet Forwarding Engine (PFE) de Juniper Networks Junos OS permite a un atacante no autenticado basado en la red causar una Denegación de Servicio (DoS). En las series SRX5000 con SPC3, SRX4000 y vSRX, cuando es configurado PowerMode IPsec y es recibido un paquete ESP malformado que coincide con un túnel IPsec establecido, el PFE es bloqueado. Este problema afecta a Juniper Networks Junos OS en las series SRX5000 con SPC3, SRX4000 y vSRX: Todas las versiones anteriores a 19.4R2-S6, 19.4R3-S7; las versiones 20.1 anteriores a 20.1R3-S3; las versiones 20.2 anteriores a 20.2R3-S4; las versiones 20.3 anteriores a 20.3R3-S3; las versiones 20.4 anteriores a 20.4R3-S2; las versiones 21.1 anteriores a 21.1R3; las versiones 21.2 anteriores a 21.2R3; las versiones 21.3 anteriores a 21.3R1-S2, 21.3R2
