Summary
An Improper Check for Unusual or Exceptional Conditions vulnerability in the flow daemon (flowd) of Juniper Networks Junos OS on
SRX4600 and SRX5000 Series
allows an attacker to send TCP packets with
SYN/FIN or SYN/RST
flags, bypassing the expected blocking of these packets.
A TCP packet with SYN/FIN or SYN/RST should be dropped in flowd. However, when no-syn-check and Express Path are enabled, these TCP packets are unexpectedly transferred to the downstream network.
This issue affects Junos OS on SRX4600 and SRX5000 Series:
* All versions before 21.2R3-S8,
* from 21.4 before 21.4R3-S7,
* from 22.1 before 22.1R3-S6,
* from 22.2 before 22.2R3-S4,
* from 22.3 before 22.3R3-S3,
* from 22.4 before 22.4R3-S2,
* from 23.2 before 23.2R2,
* from 23.4 before 23.4R1-S1, 23.4R2.

"value": "Una vulnerabilidad de verificaci\u00f3n inadecuada de condiciones inusuales o excepcionales en el demonio de flujo (flowd) de Juniper Networks Junos OS en las series SRX4600 y SRX5000 permite a un atacante enviar paquetes TCP con indicadores SYN/FIN o SYN/RST, evitando el bloqueo esperado de estos paquetes. . Un paquete TCP con SYN/FIN o SYN/RST debe descartarse en flowd. Sin embargo, cuando no-syn-check y Express Path est\u00e1n habilitados, estos paquetes TCP se transfieren inesperadamente a la red descendente.
