Severity
Summary
A vulnerability in h2oai/h2o-3 version 3.46.0.1 allows remote attackers to write arbitrary data to any file on the server. This is achieved by exploiting the `/3/Parse` endpoint to inject attacker-controlled data as the header of an empty file, which is then exported using the `/3/Frames/framename/export` endpoint. The impact of this vulnerability includes the potential for remote code execution and complete access to the system running h2o-3, as attackers can overwrite critical files such as private SSH keys or script files.

"value": "Una vulnerabilidad en h2oai/h2o-3 versi\u00f3n 3.46.0.1 permite a atacantes remotos escribir datos arbitrarios en cualquier archivo del servidor. Esto se logra explotando el endpoint \u0027/3/Parse\u0027 para inyectar datos controlados por el atacante como la cabecera de un archivo vac\u00edo, que luego se exporta usando el endpoint \u0027/3/Frames/framename/export\u0027. El impacto de esta vulnerabilidad incluye el potencial de ejecuci\u00f3n remota de c\u00f3digo y acceso completo al sistema que ejecuta h2o-3, ya que los atacantes pueden sobrescribir archivos cr\u00edticos como claves SSH privadas o archivos de script."
