CVE-2025-30648

An Improper Input Validation vulnerability in the Juniper DHCP Daemon (jdhcpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause the jdhcpd process to crash resulting in a Denial of Service (DoS). When a specifically malformed DHCP packet is received from a DHCP client, the jdhcpd process crashes, which will lead to the unavailability of the DHCP service and thereby resulting in a sustained DoS. The DHCP process will restart automatically to recover the service. This issue will occur when dhcp-security is enabled. This issue affects Junos OS: * All versions before 21.2R3-S9, * from 21.4 before 21.4R3-S10, * from 22.2 before 22.2R3-S6, * from 22.4 before 22.4R3-S6, * from 23.2 before 23.2R2-S3, * from 23.4 before 23.4R2-S4, * from 24.2 before 24.2R2; Junos OS Evolved: * from 22.4 before 22.4R3-S6-EVO, * from 23.2 before 23.2R2-S3-EVO, * from 23.4 before 23.4R2-S4-EVO, * from 24.2 before 24.2R2-EVO. .

Summary		(es) Una vulnerabilidad de validación de entrada incorrecta en el demonio DHCP de Juniper (jdhcpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque el bloqueo del proceso jdhcpd, lo que resulta en una denegación de servicio (DoS). Cuando se recibe un paquete DHCP específicamente malformado de un cliente DHCP, el proceso jdhcpd se bloquea, lo que provoca la indisponibilidad del servicio DHCP y, por lo tanto, una denegación de servicio (DoS) prolongada. El proceso DHCP se reiniciará automáticamente para recuperar el servicio. Este problema ocurre cuando la seguridad DHCP está habilitada. Este problema afecta a Junos OS: * Todas las versiones anteriores a 21.2R3-S9, * desde 21.4 hasta 21.4R3-S10, * desde 22.2 hasta 22.2R3-S6, * desde 22.4 hasta 22.4R3-S6, * desde 23.2 hasta 23.2R2-S3, * desde 23.4 hasta 23.4R2-S4, * desde 24.2 hasta 24.2R2; Junos OS Evolved: * desde 22.4 hasta 22.4R3-S6-EVO, * desde 23.2 hasta 23.2R2-S3-EVO, * desde 23.4 hasta 23.4R2-S4-EVO, * desde 24.2 hasta 24.2R2-EVO.
