CVSS: 7.5EPSS: 0%CPEs: 57EXPL: 0CVE-2022-22175 – Junos OS: MX Series and SRX Series: The flowd daemon will crash if the SIP ALG is enabled and specific SIP messages are processed
https://notcve.org/view.php?id=CVE-2022-22175
An Improper Locking vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series and SRX Series allows an unauthenticated networked attacker to cause a flowprocessing daemon (flowd) crash and thereby a Denial of Service (DoS). Continued receipt of these specific packets will cause a sustained Denial of Service condition. This issue can occur in a scenario where the SIP ALG is enabled and specific SIP messages are being processed simultaneously. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R2-S2, 21.1R3; 21.2 versions prior to 21.2R1-S2, 21.2R2; 21.3 versions prior to 21.3R1-S1, 21.3R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1. • https://kb.juniper.net/JSA11281 • CWE-667: Improper Locking •
CVSS: 9.8EPSS: 0%CPEs: 160EXPL: 0CVE-2022-22167 – Junos OS: SRX Series: If no-syn-check is enabled, traffic classified as UNKNOWN gets permitted by pre-id-default-policy
https://notcve.org/view.php?id=CVE-2022-22167
A traffic classification vulnerability in Juniper Networks Junos OS on the SRX Series Services Gateways may allow an attacker to bypass Juniper Deep Packet Inspection (JDPI) rules and access unauthorized networks or resources, when 'no-syn-check' is enabled on the device. While JDPI correctly classifies out-of-state asymmetric TCP flows as the dynamic-application UNKNOWN, this classification is not provided to the policy module properly and hence traffic continues to use the pre-id-default-policy, which is more permissive, causing the firewall to allow traffic to be forwarded that should have been denied. This issue only occurs when 'set security flow tcp-session no-syn-check' is configured on the device. This issue affects Juniper Networks Junos OS on SRX Series: 18.4 versions prior to 18.4R2-S10, 18.4R3-S10; 19.1 versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S3; 19.4 versions prior to 19.4R3-S5; 20.1 versions prior to 20.1R3-S1; 20.2 versions prior to 20.2R3-S2; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R2-S2, 20.4R3; 21.1 versions prior to 21.1R2-S2, 21.1R3; 21.2 versions prior to 21.2R2.

CVSS: 7.5EPSS: 0%CPEs: 104EXPL: 0CVE-2022-22153 – SRX Series and MX Series with SPC3: A high percentage of fragments might lead to high latency or packet drops
https://notcve.org/view.php?id=CVE-2022-22153
An Insufficient Algorithmic Complexity combined with an Allocation of Resources Without Limits or Throttling vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 allows an unauthenticated network attacker to cause latency in transit packet processing and even packet loss. If transit traffic includes a significant percentage (> 5%) of fragmented packets which need to be reassembled, high latency or packet drops might be observed. This issue affects Juniper Networks Junos OS on SRX Series, MX Series with SPC3: All versions prior to 18.2R3; 18.3 versions prior to 18.3R3; 18.4 versions prior to 18.4R2-S9, 18.4R3; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S1, 19.2R2. Una Complejidad Algorítmica no Suficiente Combinada con una vulnerabilidad de Asignación de Recursos sin Límites o Estrangulamiento en el demonio de procesamiento de flujos (flowd) de Junos OS de Juniper Networks en las series SRX y MX con SPC3 permite a un atacante de red no autenticado causar latencia en el procesamiento de paquetes en tránsito e incluso la pérdida de paquetes. Si el tráfico de tránsito incluye un porcentaje significativo (más del 5%) de paquetes fragmentados que deben volver a ensamblarse, puede observarse una alta latencia o pérdidas de paquetes. • https://kb.juniper.net/JSA11261 • CWE-407: Inefficient Algorithmic Complexity CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 10.0EPSS: 0%CPEs: 13EXPL: 0CVE-2021-31384 – Junos OS: SRX Series: Under a specific device configuration an attacker can access the devices J-Web management services from any interface, regardless of security settings protecting the service
https://notcve.org/view.php?id=CVE-2021-31384
Due to a Missing Authorization weakness and Insufficient Granularity of Access Control in a specific device configuration, a vulnerability exists in Juniper Networks Junos OS on SRX Series whereby an attacker who attempts to access J-Web administrative interfaces can successfully do so from any device interface regardless of the web-management configuration and filter rules which may otherwise protect access to J-Web. This issue affects: Juniper Networks Junos OS SRX Series 20.4 version 20.4R1 and later versions prior to 20.4R2-S1, 20.4R3; 21.1 versions prior to 21.1R1-S1, 21.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1. Debido a una debilidad de Autorización Faltante y a una Granularidad Insuficiente del Control de Acceso en una configuración de dispositivo específica, se presenta una vulnerabilidad en Juniper Networks Junos OS en la serie SRX por la a un atacante que intente acceder a las interfaces administrativas de J-Web puede hacerlo con éxito desde cualquier interfaz de dispositivo, independientemente de la configuración de administración web y de las reglas de filtrado que pueden proteger el acceso a J-Web.
