CVE-2023-22405 – Junos OS: QFX5k Series, EX46xx Series: MAC limiting feature stops working after PFE restart or device reboot
https://notcve.org/view.php?id=CVE-2023-22405
An Improper Preservation of Consistency Between Independent Representations of Shared State vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS) to device due to out of resources. When a device is configured with "service-provider/SP style" switching, and mac-limiting is configured on an Aggregated Ethernet (ae) interface, and then a PFE is restarted or the device is rebooted, mac-limiting doesn't work anymore. Please note that the issue might not be apparent as traffic will continue to flow through the device although the mac table and respective logs will indicate that mac limit is reached. Functionality can be restored by removing and re-adding the MAC limit configuration. This issue affects Juniper Networks Junos OS on QFX5k Series, EX46xx Series: All versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S3; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3 on; 21.4 versions prior to 21.4R3 on; 22.1 versions prior to 22.1R2 on. • https://kb.juniper.net/JSA70201 • CWE-1250: Improper Preservation of Consistency Between Independent Representations of Shared State •
CVE-2022-22226 – Junos OS: EX4300-MP, EX4600, QFX5000 Series: In VxLAN scenarios specific packets processed cause a memory leak leading to a PFE crash
https://notcve.org/view.php?id=CVE-2022-22226
In VxLAN scenarios on EX4300-MP, EX4600, QFX5000 Series devices an Uncontrolled Memory Allocation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated adjacently located attacker sending specific packets to cause a Denial of Service (DoS) condition by crashing one or more PFE's when they are received and processed by the device. Upon automatic restart of the PFE, continued processing of these packets will cause the memory leak to reappear. Depending on the volume of packets received the attacker may be able to create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on EX4300-MP, EX4600, QFX5000 Series: 17.1 version 17.1R1 and later versions prior to 17.3R3-S12; 17.4 versions prior to 17.4R2-S13, 17.4R3-S5; 18.1 versions prior to 18.1R3-S13; 18.2 versions prior to 18.2R3-S8; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R1-S8, 18.4R2-S6, 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R1-S7, 19.2R3-S1; 19.3 versions prior to 19.3R2-S6, 19.3R3-S1; 19.4 versions prior to 19.4R1-S4, 19.4R2-S4, 19.4R3-S1; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2-S3, 20.2R3; 20.3 versions prior to 20.3R2. This issue does not affect Junos OS versions prior to 17.1R1. • https://kb.juniper.net/JSA69876 https://www.juniper.net/documentation/us/en/software/junos/ovsdb-vxlan/evpn-vxlan/topics/ref/statement/vxlan.html#id-vxlan__d281e31 • CWE-770: Allocation of Resources Without Limits or Throttling CWE-789: Memory Allocation with Excessive Size Value •
CVE-2022-22221 – Junos OS: SRX and EX Series: Local privilege escalation flaw in "download" functionality
https://notcve.org/view.php?id=CVE-2022-22221
An Improper Neutralization of Special Elements vulnerability in the download manager of Juniper Networks Junos OS on SRX Series and EX Series allows a locally authenticated attacker with low privileges to take full control over the device. One aspect of this vulnerability is that the attacker needs to be able to execute any of the "request ..." or "show system download ..." commands. This issue affects Juniper Networks Junos OS on SRX Series and EX Series: All versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2, 20.4R3-S3; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R2-S2, 21.2R3; 21.3 versions prior to 21.3R2, 21.3R3; 21.4 versions prior to 21.4R1-S1, 21.4R2. Una vulnerabilidad de Neutralización Inapropiada de Elementos Especiales en el administrador de descargas del Sistema Operativo Junos de Juniper Networks en las series SRX y EX permite a un atacante autenticado localmente con bajos privilegios tomar el control total del dispositivo. Uno de los aspectos de esta vulnerabilidad es que el atacante debe ser capaz de ejecutar cualquiera de los comandos "request ..." o "show system download ...". • https://kb.juniper.net/JSA69725 •
CVE-2022-22203 – Junos OS: EX4600 Series and QFX5000 Series: Receipt of specific traffic will lead to an fxpc process crash followed by an FPC reboot
https://notcve.org/view.php?id=CVE-2022-22203
An Incorrect Comparison vulnerability in PFE of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a Denial of Service (DoS). On QFX5000 Series, and EX4600 and EX4650 platforms, the fxpc process will crash followed by the FPC reboot upon receipt of a specific hostbound packet. Continued receipt of these specific packets will create a sustained Denial of Service (DoS) condition. This issue only affects Juniper Networks Junos OS 19.4 version 19.4R3-S4. Una vulnerabilidad de comparación incorrecta en PFE del Sistema Operativo Junos de Juniper Networks permite a un atacante adyacente no autenticado causar una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69707 • CWE-697: Incorrect Comparison •

https://notcve.org/view.php?id=CVE-2022-22188
An Uncontrolled Memory Allocation vulnerability leading to a Heap-based Buffer Overflow in the packet forwarding engine (PFE) of Juniper Networks Junos OS allows a network-based unauthenticated attacker to flood the device with traffic leading to a Denial of Service (DoS). The device must be configured with storm control profiling limiting the number of unknown broadcast, multicast, or unicast traffic to be vulnerable to this issue. This issue affects: Juniper Networks Junos OS on QFX5100/QFX5110/QFX5120/QFX5200/QFX5210/EX4600/EX4650 Series; 20.2 version 20.2R1 and later versions prior to 20.2R2. This issue does not affect: Juniper Networks Junos OS versions prior to 20.2R1. Una vulnerabilidad de Asignación de Memoria no Controlada conllevando a un desbordamiento del búfer en la región Heap de la memoria en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS permite a un atacante no autenticado basado en la red inundar el dispositivo con tráfico, conllevando a una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69497 • CWE-122: Heap-based Buffer Overflow CWE-789: Memory Allocation with Excessive Size Value •
