CVE-2024-30395 – Junos OS and Junos OS Evolved: A malformed BGP tunnel encapsulation attribute will lead to an rpd crash
https://notcve.org/view.php?id=CVE-2024-30395
An Improper Validation of Specified Type of Input vulnerability in Routing Protocol Daemon (RPD) of Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). If a BGP update is received over an established BGP session which contains a tunnel encapsulation attribute with a specifically malformed TLV, rpd will crash and restart. This issue affects: Junos OS: * all versions before 21.2R3-S7, * from 21.3 before 21.3R3-S5, * from 21.4 before 21.4R3-S5, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3, * from 23.2 before 23.2R1-S2, 23.2R2. Junos OS Evolved: * all versions before 21.2R3-S7-EVO, * from 21.3-EVO before 21.3R3-S5-EVO, * from 21.4-EVO before 21.4R3-S5-EVO, * from 22.2-EVO before 22.2R3-S3-EVO, * from 22.3-EVO before 22.3R3-S2-EVO, * from 22.4-EVO before 22.4R3-EVO, * from 23.2-EVO before 23.2R1-S2-EVO, 23.2R2-EVO. This is a related but separate issue than the one described in JSA75739 Una validación inadecuada de una vulnerabilidad de tipo específico de entrada en el daemon de protocolo de enrutamiento (RPD) de Junos OS y Junos OS Evolved permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). Si se recibe una actualización de BGP a través de una sesión BGP establecida que contiene un atributo de encapsulación de túnel con un TLV específicamente mal formado, rpd fallará y se reiniciará. Este problema afecta a: Junos OS: * todas las versiones anteriores a 21.2R3-S7, * desde 21.3 anterior a 21.3R3-S5, * desde 21.4 anterior a 21.4R3-S5, * desde 22.1 anterior a 22.1R3-S5, * desde 22.2 anterior a 22.2R3- S3, * desde 22.3 antes de 22.3R3-S2, * desde 22.4 antes de 22.4R3, * desde 23.2 antes de 23.2R1-S2, 23.2R2.

CVE-2024-30405 – Junos OS: SRX 5000 Series with SPC2: Processing of specific crafted packets when ALG is enabled causes a transit traffic Denial of Service
https://notcve.org/view.php?id=CVE-2024-30405
An Incorrect Calculation of Buffer Size vulnerability in Juniper Networks Junos OS SRX 5000 Series devices using SPC2 line cards while ALGs are enabled allows an attacker sending specific crafted packets to cause a transit traffic Denial of Service (DoS). Continued receipt and processing of these specific packets will sustain the Denial of Service condition. This issue affects: Juniper Networks Junos OS SRX 5000 Series with SPC2 with ALGs enabled. * All versions earlier than 21.2R3-S7; * 21.4 versions earlier than 21.4R3-S6; * 22.1 versions earlier than 22.1R3-S5; * 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 23.2R2.

CVE-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.

CVE-2024-21615 – Junos OS and Junos OS Evolved: A low-privileged user can access confidential information
https://notcve.org/view.php?id=CVE-2024-21615
An Incorrect Default Permissions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to access confidential information on the system. On all Junos OS and Junos OS Evolved platforms, when NETCONF traceoptions are configured, and a super-user performs specific actions via NETCONF, then a low-privileged user can access sensitive information compromising the confidentiality of the system. This issue affects: Junos OS: * all versions before 21.2R3-S7, * from 21.4 before 21.4R3-S5, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3, * from 23.2 before 23.2R1-S2.

CVE-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 •
