CVSS: 7.1EPSS: 0%CPEs: 14EXPL: 0CVE-2024-21618 – Junos OS and Junos OS Evolved: When LLDP is enabled and a malformed LLDP packet is received, l2cpd crashes
https://notcve.org/view.php?id=CVE-2024-21618
An Access of Memory Location After End of Buffer vulnerability in the Layer-2 Control Protocols Daemon (l2cpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when LLDP is enabled on a specific interface, and a malformed LLDP packet is received, l2cpd crashes and restarts. The impact of the l2cpd crash is reinitialization of STP protocols (RSTP, MSTP or VSTP), and MVRP and ERP. Also, if any services depend on LLDP state (like PoE or VoIP device recognition), then these will also be affected. This issue affects: Junos OS: * from 21.4 before 21.4R3-S4, * from 22.1 before 22.1R3-S4, * from 22.2 before 22.2R3-S2, * from 22.3 before 22.3R2-S2, 22.3R3-S1, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2.

CVSS: 5.3EPSS: 0%CPEs: 10EXPL: 0CVE-2024-21610 – Junos OS: MX Series: In a scaled subscriber scenario if CoS information is gathered mgd processes gets stuck
https://notcve.org/view.php?id=CVE-2024-21610
An Improper Handling of Exceptional Conditions vulnerability in the Class of Service daemon (cosd) of Juniper Networks Junos OS on MX Series allows an authenticated, network-based attacker with low privileges to cause a limited Denial of Service (DoS). In a scaled subscriber scenario when specific low privileged commands, received over NETCONF, SSH or telnet, are handled by cosd on behalf of mgd, the respective child management daemon (mgd) processes will get stuck. In case of (Netconf over) SSH this leads to stuck SSH sessions, so that when the connection-limit for SSH is reached new sessions can't be established anymore. A similar behavior will be seen for telnet etc. Stuck mgd processes can be monitored by executing the following command: user@host> show system processes extensive | match mgd | match sbwait This issue affects Juniper Networks Junos OS on MX Series: All versions earlier than 20.4R3-S9; 21.2 versions earlier than 21.2R3-S7; 21.3 versions earlier than 21.3R3-S5; 21.4 versions earlier than 21.4R3-S5; 22.1 versions earlier than 22.1R3-S4; 22.2 versions earlier than 22.2R3-S3; 22.3 versions earlier than 22.3R3-S2; 22.4 versions earlier than 22.4R3; 23.2 versions earlier than 23.2R1-S2, 23.2R2. Una vulnerabilidad de manejo inadecuado de condiciones excepcionales en el daemon de clase de servicio (cosd) de Juniper Networks Junos OS en la serie MX permite que un atacante autenticado basado en red con privilegios bajos cause una denegación de servicio (DoS) limitada. En un escenario de suscriptor escalado, cuando cosd maneja comandos específicos de privilegios bajos, recibidos a través de NETCONF, SSH o telnet, en nombre de mgd, los respectivos procesos del daemon de administración infantil (mgd) se atascarán. • http://supportportal.juniper.net/JSA75751 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.1EPSS: 0%CPEs: 10EXPL: 0CVE-2024-21609 – Junos OS: MX Series with SPC3, and SRX Series: If specific IPsec parameters are negotiated iked will crash due to a memory leak
https://notcve.org/view.php?id=CVE-2024-21609
A Missing Release of Memory after Effective Lifetime vulnerability in the IKE daemon (iked) of Juniper Networks Junos OS on MX Series with SPC3, and SRX Series allows an administratively adjacent attacker which is able to successfully establish IPsec tunnels to cause a Denial of Service (DoS). If specific values for the IPsec parameters local-ip, remote-ip, remote ike-id, and traffic selectors are sent from the peer, a memory leak occurs during every IPsec SA rekey which is carried out with a specific message sequence. This will eventually result in an iked process crash and restart. The iked process memory consumption can be checked using the below command: user@host> show system processes extensive | grep iked PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND 56903 root 31 0 4016M 2543M CPU0 0 2:10 10.50% iked This issue affects Juniper Networks Junos OS: * All versions earlier than 20.4R3-S9; * 21.2 versions earlier than 21.2R3-S7; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S4; * 22.1 versions earlier than 22.1R3-S3; * 22.2 versions earlier than 22.2R3-S2; * 22.3 versions earlier than 22.3R3; * 22.4 versions earlier than 22.4R3; * 23.2 versions earlier than 23.2R1-S2, 23.2R2. Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en el daemon IKE (iked) de Juniper Networks Junos OS en la serie MX con SPC3 y la serie SRX permite que un atacante administrativamente adyacente que pueda establecer con éxito túneles IPsec provoque una denegación de servicio ( DoS). Si el par envía valores específicos para los parámetros IPsec local-ip, remoto-ip, remoto ike-id y selectores de tráfico, se produce una pérdida de memoria durante cada nueva clave de IPsec SA que se lleva a cabo con una secuencia de mensajes específica. Esto eventualmente resultará en un bloqueo y reinicio del proceso iked. • http://supportportal.juniper.net/JSA75750 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-21605 – Junos OS: SRX 300 Series: Specific link local traffic causes a control plane overload
https://notcve.org/view.php?id=CVE-2024-21605
An Exposure of Resource to Wrong Sphere vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX 300 Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). Specific valid link-local traffic is not blocked on ports in STP blocked state but is instead sent to the control plane of the device. This leads to excessive resource consumption and in turn severe impact on all control and management protocols of the device. This issue affects Juniper Networks Junos OS: * 21.2 version 21.2R3-S3 and later versions earlier than 21.2R3-S6; * 22.1 version 22.1R3 and later versions earlier than 22.1R3-S4; * 22.2 version 22.2R2 and later versions earlier than 22.2R3-S2; * 22.3 version 22.3R2 and later versions earlier than 22.3R3-S1; * 22.4 versions earlier than 22.4R2-S2, 22.4R3; * 23.2 versions earlier than 23.2R1-S1, 23.2R2. This issue does not affect Juniper Networks Junos OS 21.4R1 and later versions of 21.4. Una vulnerabilidad de exposición de recursos a una esfera incorrecta en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS en la serie SRX 300 permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). El tráfico de enlace local válido específico no se bloquea en los puertos en estado bloqueado STP, sino que se envía al plano de control del dispositivo. Esto conduce a un consumo excesivo de recursos y, a su vez, a un impacto severo en todos los protocolos de control y gestión del dispositivo. • https://supportportal.juniper.net/JSA75746 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-668: Exposure of Resource to Wrong Sphere •
