CVE-2025-3026

The vulnerability exists in the EJBCA service, version 8.0 Enterprise. Not tested in higher versions. By modifying the ‘Host’ header in an HTTP request, it is possible to manipulate the generated links and thus redirect the client to a different base URL. In this way, an attacker could insert his own server for the client to send HTTP requests, provided he succeeds in exploiting it.

Summary		(es) La vulnerabilidad existe en el servicio EJBCA, versión 8.0 Enterprise. No se ha probado en versiones superiores. Al modificar el encabezado "Host" en una solicitud HTTP, es posible manipular los enlaces generados y, por lo tanto, redirigir al cliente a una URL base diferente. De esta forma, un atacante podría insertar su propio servidor para que el cliente envíe solicitudes HTTP, si logra explotarlo.
