CVE-2025-13914

A Key Exchange without Entity Authentication vulnerability in the SSH implementation of Juniper Networks Apstra allows a unauthenticated, MITM attacker to impersonate managed devices. Due to insufficient SSH host key validation an attacker can perform a machine-in-the-middle attack on the SSH connections from Apstra to managed devices, enabling an attacker to impersonate a managed device and capture user credentials. This issue affects all versions of Apstra before 6.1.1.

Summary		(es) Una vulnerabilidad de intercambio de claves sin autenticación de entidad en la implementación SSH de Juniper Networks Apstra permite a un atacante no autenticado, MitM, suplantar dispositivos gestionados. Debido a una validación insuficiente de la clave de host SSH, un atacante puede realizar un ataque MitM en las conexiones SSH de Apstra a los dispositivos gestionados, lo que permite a un atacante suplantar un dispositivo gestionado y capturar credenciales de usuario. Este problema afecta a todas las versiones de Apstra anteriores a la 6.1.1.
