CVSS: 7.1EPSS: 0%CPEs: 16EXPL: 0CVE-2024-39556 – Junos OS and Junos OS Evolved: Loading a malicious certificate from the CLI may result in a stack-based overflow
https://notcve.org/view.php?id=CVE-2024-39556
A Stack-Based Buffer Overflow vulnerability in Juniper Networks Junos OS and Juniper Networks Junos OS Evolved may allow a local, low-privileged attacker with access to the CLI the ability to load a malicious certificate file, leading to a limited Denial of Service (DoS) or privileged code execution. By exploiting the 'set security certificates' command with a crafted certificate file, a malicious attacker with access to the CLI could cause a crash of the command management daemon (mgd), limited to the local user's command interpreter, or potentially trigger a stack-based buffer overflow. This issue affects: Junos OS: * All versions before 21.4R3-S7, * from 22.1 before 22.1R3-S6, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S1, 23.4R2; Junos OS Evolved: * All versions before 21.4R3-S7-EVO, * from 22.1-EVO before 22.1R3-S6-EVO, * from 22.2-EVO before 22.2R3-S4-EVO, * from 22.3-EVO before 22.3R3-S3-EVO, * from 22.4-EVO before 22.4R3-S2-EVO, * from 23.2-EVO before 23.2R2-EVO, * from 23.4-EVO before 23.4R1-S1-EVO, 23.4R2-EVO. Una vulnerabilidad de desbordamiento de búfer basado en pila en Juniper Networks Junos OS y Juniper Networks Junos OS Evolved puede permitir que un atacante local con pocos privilegios y acceso a la CLI tenga la capacidad de cargar un archivo de certificado malicioso, lo que lleva a una denegación de servicio (DoS) limitada. ) o ejecución de código privilegiado. • https://supportportal.juniper.net/JSA83016 • CWE-121: Stack-based Buffer Overflow •
CVSS: 8.7EPSS: 0%CPEs: 14EXPL: 0CVE-2024-39555 – Junos OS and Junos OS Evolved: Receipt of a specific malformed BGP update causes the session to reset
https://notcve.org/view.php?id=CVE-2024-39555
An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker sending a specific malformed BGP update message to cause the session to reset, resulting in a Denial of Service (DoS). Continued receipt and processing of these malformed BGP update messages will create a sustained Denial of Service (DoS) condition. Upon receipt of a BGP update message over an established BGP session containing a specifically malformed tunnel encapsulation attribute, when segment routing is enabled, internal processing of the malformed attributes within the update results in improper parsing of remaining attributes, leading to session reset: BGP SEND Notification code 3 (Update Message Error) subcode 1 (invalid attribute list) Only systems with segment routing enabled are vulnerable to this issue. This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations, and requires a remote attacker to have at least one established BGP session. This issue affects: Junos OS: * All versions before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2. Junos OS Evolved: * All versions before 21.4R3-S8-EVO, * from 22.2-EVO before 22.2R3-S4-EVO, * from 22.3-EVO before 22.3R3-S3-EVO, * from 22.4-EVO before 22.4R3-S3-EVO, * from 23.2-EVO before 23.2R2-S1-EVO, * from 23.4-EVO before 23.4R1-S2-EVO, 23.4R2-EVO. Una vulnerabilidad de manejo inadecuado de condiciones excepcionales en el daemon de protocolo de enrutamiento (RPD) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante envíe un mensaje específico de actualización de BGP con formato incorrecto para provocar que la sesión se reinicie, lo que resulta en una denegación de servicio (DoS). La recepción y el procesamiento continuos de estos mensajes de actualización de BGP con formato incorrecto crearán una condición sostenida de denegación de servicio (DoS). Al recibir un mensaje de actualización de BGP a través de una sesión BGP establecida que contiene un atributo de encapsulación de túnel específicamente mal formado, cuando el enrutamiento de segmento está habilitado, el procesamiento interno de los atributos mal formados dentro de la actualización da como resultado un análisis inadecuado de los atributos restantes, lo que lleva al restablecimiento de la sesión: BGP SEND Código de notificación 3 (Error de mensaje de actualización) subcódigo 1 (lista de atributos no válidos) Solo los sistemas con enrutamiento de segmentos habilitado son vulnerables a este problema. • https://supportportal.juniper.net/JSA83015 • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 8.2EPSS: 0%CPEs: 16EXPL: 0CVE-2024-39554 – Junos OS and Junos OS Evolved: BGP multipath incremental calculation is resulting in an rpd crash
https://notcve.org/view.php?id=CVE-2024-39554
A Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to inject incremental routing updates when BGP multipath is enabled, causing rpd to crash and restart, resulting in a Denial of Service (DoS). Since this is a timing issue (race condition), the successful exploitation of this vulnerability is outside the attacker's control. However, continued receipt and processing of this packet may create a sustained Denial of Service (DoS) condition. On all Junos OS and Junos OS Evolved platforms with BGP multipath enabled, a specific multipath calculation removes the original next hop from the multipath lead routes nexthop-set. ... Dado que se trata de una cuestión de tiempo (condición de ejecución), la explotación exitosa de esta vulnerabilidad está fuera del control del atacante. Sin embargo, la recepción y el procesamiento continuo de este paquete pueden crear una condición sostenida de Denegación de Servicio (DoS). • https://supportportal.juniper.net/JSA83014 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
