CVE-2024-39534

An Incorrect Comparison vulnerability in the local address verification API of Juniper Networks Junos OS Evolved allows an unauthenticated network-adjacent attacker to create sessions or send traffic to the device using the network and broadcast address of the subnet assigned to an interface. This is unintended and unexpected behavior and can allow an attacker to bypass certain compensating controls, such as stateless firewall filters. This issue affects Junos OS Evolved: * All versions before 21.4R3-S8-EVO, * 22.2-EVO before 22.2R3-S4-EVO, * 22.3-EVO before 22.3R3-S4-EVO, * 22.4-EVO before 22.4R3-S3-EVO, * 23.2-EVO before 23.2R2-S1-EVO, * 23.4-EVO before 23.4R1-S2-EVO, 23.4R2-EVO.

Summary		(es) Una vulnerabilidad de comparación incorrecta en la API de verificación de dirección local de Juniper Networks Junos OS Evolved permite que un atacante no autenticado adyacente a la red cree sesiones o envíe tráfico al dispositivo utilizando la dirección de red y de difusión de la subred asignada a una interfaz. Este es un comportamiento no deseado e inesperado y puede permitir que un atacante eluda ciertos controles de compensación, como filtros de firewall sin estado. Este problema afecta a Junos OS Evolved: * Todas las versiones anteriores a 21.4R3-S8-EVO, * 22.2-EVO anteriores a 22.2R3-S4-EVO, * 22.3-EVO anteriores a 22.3R3-S4-EVO, * 22.4-EVO anteriores a 22.4R3-S3-EVO, * 23.2-EVO anteriores a 23.2R2-S1-EVO, * 23.4-EVO anteriores a 23.4R1-S2-EVO, 23.4R2-EVO.
