CVSS: 8.8EPSS: 0%CPEs: 102EXPL: 0CVE-2023-44182 – Junos OS and Junos OS Evolved: An Unchecked Return Value in multiple users interfaces affects confidentiality and integrity of device operations
https://notcve.org/view.php?id=CVE-2023-44182
An Unchecked Return Value vulnerability in the user interfaces to the Juniper Networks Junos OS and Junos OS Evolved, the CLI, the XML API, the XML Management Protocol, the NETCONF Management Protocol, the gNMI interfaces, and the J-Web User Interfaces causes unintended effects such as demotion or elevation of privileges associated with an operators actions to occur. Multiple scenarios may occur; for example: privilege escalation over the device or another account, access to files that should not otherwise be accessible, files not being accessible where they should be accessible, code expected to run as non-root may run as root, and so forth. This issue affects: Juniper Networks Junos OS * All versions prior to 20.4R3-S7; * 21.1 versions prior to 21.1R3-S5; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R3-S2; * 22.2 versions prior to 22.2R2-S2, 22.2R3; * 22.3 versions prior to 22.3R1-S2, 22.3R2. Juniper Networks Junos OS Evolved * All versions prior to 21.4R3-S3-EVO; * 22.1-EVO version 22.1R1-EVO and later versions prior to 22.2R2-S2-EVO, 22.2R3-EVO; * 22.3-EVO versions prior to 22.3R1-S2-EVO, 22.3R2-EVO. Una vulnerabilidad de valor de retorno no verificado en las interfaces de usuario de Juniper Networks Junos OS y Junos OS Evolved, el CLI, la API XML, el protocolo de administración XML, el protocolo de administración NETCONF, las interfaces gNMI y las interfaces de usuario J-Web provoca causas no deseadas. Se producirán efectos tales como degradación o elevación de privilegios asociados con las acciones de un operador. Pueden ocurrir múltiples escenarios; por ejemplo: escalada de privilegios sobre el dispositivo u otra cuenta, acceso a archivos que de otro modo no deberían ser accesibles, archivos que no son accesibles donde deberían serlo, código que se espera que se ejecute como no root puede ejecutarse como root, etc. Este problema afecta a: Juniper Networks Junos OS * Todas las versiones anteriores a 20.4R3-S7; * Versiones 21.1 anteriores a 21.1R3-S5; * Versiones 21.2 anteriores a 21.2R3-S5; * Versiones 21.3 anteriores a 21.3R3-S4; * Versiones 21.4 anteriores a 21.4R3-S3; * Versiones 22.1 anteriores a 22.1R3-S2; * Versiones 22.2 anteriores a 22.2R2-S2, 22.2R3; * Versiones 22.3 anteriores a 22.3R1-S2, 22.3R2. • https://supportportal.juniper.net/JSA73149 https://www.juniper.net/documentation/en_US/junos/topics/concept/junos-software-user-interfaces-overview.html https://www.juniper.net/documentation/us/en/software/junos/interfaces-telemetry/topics/concept/junos-telemetry-interface-grpc-sensors.html • CWE-252: Unchecked Return Value •

https://notcve.org/view.php?id=CVE-2023-44178
A Stack-based Buffer Overflow vulnerability in the CLI command of Juniper Networks Junos OS allows a low privileged attacker to execute a specific CLI commands leading to Denial of Service. Repeated actions by the attacker will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks: Junos OS * All versions prior to 19.1R3-S10; * 19.2 versions prior to 19.2R3-S7; * 19.3 versions prior to 19.3R3-S8; * 19.4 versions prior to 19.4R3-S12; * 20.2 versions prior to 20.2R3-S8; * 20.4 versions prior to 20.4R3-S8; * 21.2 versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R3-S1; * 22.4 versions prior to 22.4R2-S1; * 23.2 versions prior to 23.2R2. Una vulnerabilidad de desbordamiento de búfer en el comando CLI de Juniper Networks Junos OS permite a un atacante con pocos privilegios ejecutar comandos CLI específicos que conducen a una Denegación de Servicio.

CVSS: 6.5EPSS: 0%CPEs: 155EXPL: 0CVE-2023-36839 – Junos OS and Junos OS Evolved: An l2cpd crash will occur when specific LLDP packets are received
https://notcve.org/view.php?id=CVE-2023-36839
An Improper Validation of Specified Quantity in Input vulnerability in the Layer-2 control protocols daemon (l2cpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker who sends specific LLDP packets to cause a Denial of Service(DoS). This issue occurs when specific LLDP packets are received and telemetry polling is being done on the device. 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: Juniper Networks Junos OS * All versions prior to 20.4R3-S8; * 21.1 version 21.1R1 and later versions; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R3-S2; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R2-S2; * 22.4 versions prior to 22.4R2; Juniper Networks Junos OS Evolved * All versions prior to 20.4R3-S8-EVO; * 21.1 version 21.1R1-EVO and later versions; * 21.2 versions prior to 21.2R3-S5-EVO; * 21.3 versions prior to 21.3R3-S4-EVO; * 21.4 versions prior to 21.4R3-S3-EVO; * 22.1 versions prior to 22.1R3-S2-EVO; * 22.2 versions prior to 22.2R3-EVO; * 22.3 versions prior to 22.3R2-S2-EVO; * 22.4 versions prior to 22.4R1-S1-EVO; Una validación inadecuada de la vulnerabilidad de cantidad especificada en la entrada en Layer-2 control protocols daemon (l2cpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado que envía paquetes LLDP específicos provoque una Denegación de Servicio (DoS). Este problema ocurre cuando se reciben paquetes LLDP específicos y se realiza un sondeo de telemetría en el dispositivo. El impacto del fallo de l2cpd es la reinicialización de los protocolos STP (RSTP, MSTP o VSTP) y MVRP y ERP. • https://supportportal.juniper.net/JSA73171 • CWE-1284: Improper Validation of Specified Quantity in Input •
