      "value": "An acceptance of extraneous untrusted data with trusted data vulnerability has been identified in Moxa’s Ethernet switches, which allows attackers with administrative privileges to manipulate HTTP Host headers by injecting a specially crafted Host header into HTTP requests sent to an affected device’s web service. This vulnerability is classified as Host Header Injection, where invalid Host headers can manipulate to redirect users, forge links, or phishing attacks. There is no impact to the confidentiality, integrity, and availability of the affected device; no loss of confidentiality, integrity, and availability within any subsequent systems."

      "value": "Una vulnerabilidad de aceptación de datos externos no confiables con datos confiables ha sido identificada en los switches Ethernet de Moxa, lo que permite a atacantes con privilegios administrativos manipular los encabezados Host HTTP inyectando un encabezado Host especialmente diseñado en las solicitudes HTTP enviadas al servicio web de un dispositivo afectado. Esta vulnerabilidad se clasifica como Host Header Injection, donde los encabezados Host inválidos pueden manipularse para redirigir usuarios, falsificar enlaces o ataques de phishing. No hay impacto en la confidencialidad, integridad y disponibilidad del dispositivo afectado; no hay pérdida de confidencialidad, integridad y disponibilidad dentro de ningún sistema subsiguiente."
