CVSS: 6.5EPSS: 0%CPEs: 334EXPL: 0CVE-2022-22250 – Junos OS and Junos OS Evolved: An FPC crash might be seen due to an EVPN MAC entry moving from local to remote
https://notcve.org/view.php?id=CVE-2022-22250
An Improper Control of a Resource Through its Lifetime vulnerability in Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows unauthenticated adjacent attacker to cause a Denial of Service (DoS). In an EVPN-MPLS scenario, if MAC is learned locally on an access interface but later a request to delete is received indicating that the MAC was learnt remotely, this can lead to memory corruption which can result in line card crash and reload. This issue affects: Juniper Networks Junos OS All versions 17.3R1 and later versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S8; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R1-S1, 21.4R2.

CVSS: 7.3EPSS: 0%CPEs: 25EXPL: 0CVE-2022-22248 – Junos OS Evolved: Incorrect file permissions can allow low-privileged user to cause another user to execute arbitrary commands
https://notcve.org/view.php?id=CVE-2022-22248
An Incorrect Permission Assignment vulnerability in shell processing of Juniper Networks Junos OS Evolved allows a low-privileged local user to modify the contents of a configuration file which could cause another user to execute arbitrary commands within the context of the follow-on user's session. If the follow-on user is a high-privileged administrator, the attacker could leverage this vulnerability to take complete control of the target system. While this issue is triggered by a user, other than the attacker, accessing the Junos shell, an attacker simply requires Junos CLI access to exploit this vulnerability. This issue affects Juniper Networks Junos OS Evolved: 20.4-EVO versions prior to 20.4R3-S1-EVO; All versions of 21.1-EVO; 21.2-EVO versions prior to 21.2R3-EVO; 21.3-EVO versions prior to 21.3R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 19.2R1-EVO. • https://kb.juniper.net/JSA69905 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 0CVE-2022-22247 – Junos OS Evolved: Kernel processing of unvalidated TCP segments could lead to a Denial of Service (DoS)
https://notcve.org/view.php?id=CVE-2022-22247
An Improper Input Validation vulnerability in ingress TCP segment processing of Juniper Networks Junos OS Evolved allows a network-based unauthenticated attacker to send a crafted TCP segment to the device, triggering a kernel panic, leading to a Denial of Service (DoS) condition. Continued receipt and processing of this TCP segment could create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS Evolved: 21.3 versions prior to 21.3R3-EVO; 21.4 versions prior to 21.4R2-EVO; 22.1 versions prior to 22.1R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 21.3R1-EVO. Una vulnerabilidad de Comprobación de Entrada Inapropiada en el procesamiento de segmentos TCP de entrada de Juniper Networks Junos OS Evolved permite a un atacante no autenticado basado en la red enviar un segmento TCP diseñado al dispositivo, desencadenando un pánico del núcleo, conllevando a una condición de Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69904 • CWE-20: Improper Input Validation •
CVSS: 5.5EPSS: 0%CPEs: 89EXPL: 0CVE-2022-22240 – Junos OS and Junos OS Evolved: An rpd memory leak might be observed while running a specific cli command in a RIB sharding scenario
https://notcve.org/view.php?id=CVE-2022-22240
An Allocation of Resources Without Limits or Throttling and a Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated low privileged attacker to cause a Denial of Sevice (DoS). In a high-scaled BGP routing environment with rib-sharding enabled, two issues may occur when executing a specific CLI command. One is a memory leak issue with rpd where the leak rate is not constant, and the other is a temporary spike in rpd memory usage during command execution. This issue affects: Juniper Networks Junos OS 19.4 versions prior to 19.4R3-S9; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R1-S2, 21.2R2-S1, 21.2R3; 21.3 versions prior to 21.3R2.

https://notcve.org/view.php?id=CVE-2022-22239
An Execution with Unnecessary Privileges vulnerability in Management Daemon (mgd) of Juniper Networks Junos OS Evolved allows a locally authenticated attacker with low privileges to escalate their privileges on the device and potentially remote systems. This vulnerability allows a locally authenticated attacker with access to the ssh operational command to escalate their privileges on the system to root, or if there is user interaction on the local device to potentially escalate privileges on a remote system to root. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S5-EVO; 21.1-EVO versions prior to 21.1R3-EVO; 21.2-EVO versions prior to 21.2R2-S1-EVO, 21.2R3-EVO; 21.3-EVO versions prior to 21.3R2-EVO.
