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 •
CVSS: 6.1EPSS: 0%CPEs: 44EXPL: 0CVE-2023-44190 – Junos OS Evolved: PTX10001, PTX10004, PTX10008, PTX10016: MAC address validation bypass vulnerability
https://notcve.org/view.php?id=CVE-2023-44190
An Origin Validation vulnerability in MAC address validation of Juniper Networks Junos OS Evolved on PTX10001, PTX10004, PTX10008, and PTX10016 devices allows a network-adjacent attacker to bypass MAC address checking, allowing MAC addresses not intended to reach the adjacent LAN to be forwarded to the downstream network. Due to this issue, the router will start forwarding traffic if a valid route is present in forwarding-table, causing a loop and congestion in the downstream layer-2 domain connected to the device. This issue affects Juniper Networks Junos OS Evolved on PTX10001, PTX10004, PTX10008, and PTX10016: * All versions prior to 21.4R3-S5-EVO; * 22.1 versions prior to 22.1R3-S4-EVO; * 22.2 versions 22.2R1-EVO and later; * 22.3 versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO; * 22.4 versions prior to 22.4R2-S1-EVO, 22.4R3-EVO; * 23.2 versions prior to 23.2R1-S1-EVO, 23.2R2-EVO. Una vulnerabilidad de validación de origen en la validación de direcciones MAC de Juniper Networks Junos OS Evolved en dispositivos PTX10001, PTX10004, PTX10008 y PTX10016 permite que un atacante adyacente a la red omita la verificación de direcciones MAC, lo que permite reenviar direcciones MAC que no están destinadas a llegar a la LAN adyacente a la red descendente. Debido a este problema, el router comenzará a reenviar tráfico si hay una ruta válida en la tabla de reenvío, lo que provocará un bucle y una congestión en el dominio de capa 2 descendente conectado al dispositivo. Este problema afecta a Juniper Networks Junos OS Evolved en PTX10001, PTX10004, PTX10008 y PTX10016: * Todas las versiones anteriores a 21.4R3-S5-EVO; * Versiones 22.1 anteriores a 22.1R3-S4-EVO; * 22.2 versiones 22.2R1-EVO y posteriores; * Versiones 22.3 anteriores a 22.3R2-S2-EVO, 22.3R3-S1-EVO; * Versiones 22.4 anteriores a 22.4R2-S1-EVO, 22.4R3-EVO; * Versiones 23.2 anteriores a 23.2R1-S1-EVO, 23.2R2-EVO. • https://supportportal.juniper.net/JSA73154 • CWE-346: Origin Validation Error •

https://notcve.org/view.php?id=CVE-2023-44187
An Exposure of Sensitive Information vulnerability in the 'file copy' command of Junos OS Evolved allows a local, authenticated attacker with shell access to view passwords supplied on the CLI command-line. These credentials can then be used to provide unauthorized access to the remote system. This issue affects Juniper Networks Junos OS Evolved: * All versions prior to 20.4R3-S7-EVO; * 21.1 versions 21.1R1-EVO and later; * 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-S4-EVO; * 22.1 versions prior to 22.1R3-S2-EVO; * 22.2 versions prior to 22.2R2-EVO. Una vulnerabilidad de Exposición de Información Confidencial en el comando 'file copy' de Junos OS Evolved permite a un atacante local autenticado con acceso al shell ver las contraseñas proporcionadas en la línea de comandos CLI.

CVSS: 7.5EPSS: 0%CPEs: 183EXPL: 0CVE-2023-44186 – Junos OS and Junos OS Evolved: RPD crash when attempting to send a very long AS PATH to a non-4-byte-AS capable BGP neighbor
https://notcve.org/view.php?id=CVE-2023-44186
An Improper Handling of Exceptional Conditions vulnerability in AS PATH processing of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a BGP update message with an AS PATH containing a large number of 4-byte ASes, leading to a Denial of Service (DoS). Continued receipt and processing of these BGP updates will create a sustained Denial of Service (DoS) condition. This issue is hit when the router has Non-Stop Routing (NSR) enabled, has a non-4-byte-AS capable BGP neighbor, receives a BGP update message with a prefix that includes a long AS PATH containing large number of 4-byte ASes, and has to advertise the prefix towards the non-4-byte-AS capable BGP neighbor. Note: NSR is not supported on the SRX Series and is therefore not affected by this vulnerability. This issue affects: Juniper Networks Junos OS: * All versions prior to 20.4R3-S8; * 21.1 versions 21.1R1 and later; * 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-S4; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R2-S2, 22.3R3-S1; * 22.4 versions prior to 22.4R2-S1, 22.4R3. Juniper Networks Junos OS Evolved * All versions prior to 20.4R3-S8-EVO; * 21.1 versions 21.1R1-EVO and later; * 21.2 versions prior to 21.2R3-S6-EVO; * 21.3 versions prior to 21.3R3-S5-EVO; * 21.4 versions prior to 21.4R3-S5-EVO; * 22.1 versions prior to 22.1R3-S4-EVO; * 22.2 versions prior to 22.2R3-S2-EVO; * 22.3 versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO; * 22.4 versions prior to 22.4R2-S1-EVO, 22.4R3-EVO. Una vulnerabilidad de Improper Handling of Exceptional Conditions en el procesamiento AS PATH de Juniper Networks Junos OS y Junos OS Evolved permite a un atacante enviar un mensaje de actualización de BGP con un AS PATH que contiene una gran cantidad de AS de 4 bytes, lo que lleva a una Denegación de Servicio ( DoS). La recepción y el procesamiento continuo de estas actualizaciones de BGP crearán una condición sostenida de Denegación de Servicio (DoS). Este problema se produce cuando el router tiene habilitado Non-Stop Routing (NSR), tiene un vecino BGP que no es de 4 bytes con capacidad AS, recibe un mensaje de actualización de BGP con un prefijo que incluye un AS PATH largo que contiene una gran cantidad de 4 bytes. • https://supportportal.juniper.net/JSA73150 • CWE-755: Improper Handling of Exceptional Conditions •
