CVSS: 6.5EPSS: 0%CPEs: 81EXPL: 0CVE-2022-22155 – Junos OS: ACX5448: FPC memory leak due to IPv6 neighbor flaps
https://notcve.org/view.php?id=CVE-2022-22155
An Uncontrolled Resource Consumption vulnerability in the handling of IPv6 neighbor state change events in Juniper Networks Junos OS allows an adjacent attacker to cause a memory leak in the Flexible PIC Concentrator (FPC) of an ACX5448 router. The continuous flapping of an IPv6 neighbor with specific timing will cause the FPC to run out of resources, leading to a Denial of Service (DoS) condition. Once the condition occurs, further packet processing will be impacted, creating a sustained Denial of Service (DoS) condition, requiring a manual PFE restart to restore service. The following error messages will be seen after the FPC resources have been exhausted: fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 fpc0 DNX_NH::dnx_nh_tag_ipv4_hw_install(),3135: dnx_nh_tag_ipv4_hw_install: BCM L3 Egress create object failed for NH 602 (-14:No resources for operation), BCM NH Params: unit:0 Port:41, L3_INTF:0 Flags: 0x40 This issue only affects the ACX5448 router.

CVSS: 6.8EPSS: 0%CPEs: 279EXPL: 0CVE-2022-22154 – Junos Fusion: A Satellite Device can be controlled by rewiring it to a foreign AD causing a DoS
https://notcve.org/view.php?id=CVE-2022-22154
In a Junos Fusion scenario an External Control of Critical State Data vulnerability in the Satellite Device (SD) control state machine of Juniper Networks Junos OS allows an attacker who is able to make physical changes to the cabling of the device to cause a denial of service (DoS). An SD can get rebooted and subsequently controlled by an Aggregation Device (AD) which does not belong to the original Fusion setup and is just connected to an extended port of the SD. To carry out this attack the attacker needs to have physical access to the cabling between the SD and the original AD. This issue affects: Juniper Networks Junos OS 16.1R1 and later versions prior to 18.4R3-S10; 19.1 versions prior to 19.1R3-S7; 19.2 versions prior to 19.2R3-S4. This issue does not affect Juniper Networks Junos OS versions prior to 16.1R1. • https://kb.juniper.net/JSA11262 • CWE-642: External Control of Critical State Data CWE-668: Exposure of Resource to Wrong Sphere •
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 •
