Durante la auditor\u00eda se realiz\u00f3 un an\u00e1lisis de la aplicaci\u00f3n cliente aislada, escrita utilizando la biblioteca Qt y disponible para Linux, macOS, Windows, Android e iOS. Mozilla VPN opera con m\u00e1s de 400 servidores del proveedor de VPN sueco Mullvad, ubicados en m\u00e1s de 30 pa\u00edses. La conexi\u00f3n al <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/vpn\/\"   title=\"VPN\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"113\">VPN<\/a>-servicio se realiza mediante el protocolo WireGuard.    <\/p>\n<p>La auditor\u00eda fue realizada por Cure53, que previamente hab\u00eda llevado a cabo auditor\u00edas de los proyectos NTPsec, SecureDrop, Cryptocat, F-Droid y Dovecot. La auditor\u00eda abarc\u00f3 la revisi\u00f3n de los c\u00f3digos fuente y se incluy\u00f3 la realizaci\u00f3n de pruebas para identificar posibles vulnerabilidades (las cuestiones relacionadas con la criptograf\u00eda no se analizaron). Durante la revisi\u00f3n se identificaron 16 problemas de seguridad, 8 de los cuales se clasificaron como recomendaciones, 5 se asignaron un nivel bajo de peligro, 2 un nivel medio, y 1 un nivel alto.     <\/p>\n<p>Sin embargo, solo un problema con un nivel medio de riesgo fue clasificado como vulnerabilidad, ya que solo este era explotable. Este problema provocaba la filtraci\u00f3n de informaci\u00f3n sobre el uso de VPN en el c\u00f3digo para detectar un portal cautivo debido al env\u00edo de solicitudes directas no encriptadas por HTTP, transmitidas fuera del t\u00fanel VPN y exponiendo la direcci\u00f3n IP principal del usuario en caso de que un atacante pudiera controlar el tr\u00e1fico de tr\u00e1nsito. Este problema se soluciona desactivando el modo de detecci\u00f3n de portal cautivo en la configuraci\u00f3n.    <\/p>\n<p>El segundo problema de riesgo medio est&aacute; relacionado con la falta de saneamiento de los valores no num&eacute;ricos en el n&uacute;mero de puerto, lo que permite la filtraci&oacute;n de par&aacute;metros de autenticaci&oacute;n OAuth al sustituir el n&uacute;mero de puerto por una cadena del tipo &laquo;1234@example.com&raquo;, lo que resultar&aacute; en la instalaci&oacute;n de una etiqueta &lt;img src=&quot;&raquo;http:\/\/127.0.0.1:1234@example.com\/?code=&hellip;&raquo;&quot; alt=&quot;&raquo;&raquo;&quot;&gt;, que se dirige a example.com en lugar de 127.0.0.1.    <\/p>\n<p>El tercer problema, marcado como peligroso, permite que cualquier aplicaci\u00f3n local sin autenticaci\u00f3n acceda al cliente VPN a trav\u00e9s de WebSocket vinculado a localhost. Como ejemplo, se mostr\u00f3 c\u00f3mo, con el cliente VPN activo, cualquier sitio podr\u00eda organizar la creaci\u00f3n y env\u00edo de una captura de pantalla mediante la generaci\u00f3n de un evento screen_capture. Este problema no fue clasificado como vulnerabilidad, ya que el WebSocket fue utilizado solo en compilaciones de prueba internas y el uso de este canal de comunicaci\u00f3n se planeaba para el futuro para facilitar la interacci\u00f3n con la extensi\u00f3n del navegador.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
