CVE-2024-47507

An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause an integrity impact to the downstream devices. When a peer sends a BGP update message which contains the aggregator attribute with an ASN value of zero (0), rpd accepts and propagates this attribute, which can cause issues for downstream BGP peers receiving this. This issue affects: Junos OS: * All versions before 21.4R3-S6, * 22.2 versions before 22.2R3-S3, * 22.4 versions before 22.4R3; Junos OS Evolved: * All versions before 21.4R3-S7-EVO, * 22.2 versions before 22.2R3-S4-EVO, * 22.4 versions before 22.4R3-EVO.

Summary		(es) Una vulnerabilidad de verificación incorrecta de condiciones inusuales o excepcionales en el daemon de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante no autenticado basado en la red cause un impacto en la integridad de los dispositivos de bajada. Cuando un par envía un mensaje de actualización de BGP que contiene el atributo gregator con un valor ASN de cero (0), rpd acepta y propaga este atributo, lo que puede causar problemas para los pares de BGP de bajada que lo reciben. Este problema afecta a: Junos OS: * Todas las versiones anteriores a 21.4R3-S6, * Versiones 22.2 anteriores a 22.2R3-S3, * Versiones 22.4 anteriores a 22.4R3; Junos OS Evolved: * Todas las versiones anteriores a 21.4R3-S7-EVO, * Versiones 22.2 anteriores a 22.2R3-S4-EVO, * Versiones 22.4 anteriores a 22.4R3-EVO.
