https://notcve.org/view.php?id=CVE-2021-31382
On PTX1000 System, PTX10002-60C System, after upgrading to an affected release, a Race Condition vulnerability between the chassis daemon (chassisd) and firewall process (dfwd) of Juniper Networks Junos OS, may update the device's interfaces with incorrect firewall filters. This issue only occurs when upgrading the device to an affected version of Junos OS. Interfaces intended to have protections may have no protections assigned to them. Interfaces with one type of protection pattern may have alternate protections assigned to them. Interfaces intended to have no protections may have protections assigned to them. • https://kb.juniper.net/JSA11250 https://kb.juniper.net/KB10956 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 7.5EPSS: 0%CPEs: 210EXPL: 0CVE-2021-31378 – Junos OS: An attacker sending spoofed RADIUS messages to a Junos OS device configured for broadband services may cause broadband subscribers to remain stuck in a "Terminating" state.
https://notcve.org/view.php?id=CVE-2021-31378
In broadband environments, including but not limited to Enhanced Subscriber Management, (CHAP, PPP, DHCP, etc.), on Juniper Networks Junos OS devices where RADIUS servers are configured for managing subscriber access and a subscriber is logged in and then requests to logout, the subscriber may be forced into a "Terminating" state by an attacker who is able to send spoofed messages appearing to originate from trusted RADIUS server(s) destined to the device in response to the subscriber's request. These spoofed messages cause the Junos OS General Authentication Service (authd) daemon to force the broadband subscriber into this "Terminating" state which the subscriber will not recover from thereby causing a Denial of Service (DoS) to the endpoint device. Once in the "Terminating" state, the endpoint subscriber will no longer be able to access the network. Restarting the authd daemon on the Junos OS device will temporarily clear the subscribers out of the "Terminating" state. As long as the attacker continues to send these spoofed packets and subscribers request to be logged out, the subscribers will be returned to the "Terminating" state thereby creating a persistent Denial of Service to the subscriber. • https://kb.juniper.net/JSA11246 https://www.juniper.net/documentation/us/en/software/junos/subscriber-mgmt-sessions/topics/topic-map/general-authentication-service-events-tracing.html • CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2021-31377
An Incorrect Permission Assignment for Critical Resource vulnerability of a certain file in the filesystem of Junos OS allows a local authenticated attacker to cause routing process daemon (RPD) to crash and restart, causing a Denial of Service (DoS). Repeated actions by the attacker will create a sustained Denial of Service (DoS) condition.

Una vulnerabilidad de Asignación Incorrecta de Permisos para Recursos Críticos de un determinado archivo del sistema de archivos de Junos OS permite a un atacante local autenticado causar el bloqueo y el reinicio del demonio de proceso de enrutamiento (RPD), causando una Denegación de Servicio (DoS). Las acciones repetidas del atacante crearán una condición de Denegación de Servicio (DoS) sostenida. • https://kb.juniper.net/JSA11242 • CWE-732: Incorrect Permission Assignment for Critical Resource •
