"value": "BigBlueButton is an open source web conferencing system. Versions prior to 2.4.3, are subject to Insufficient Verification of Data Authenticity, resulting in Denial of Service. An attacker can make a Meteor call to `validateAuthToken` using a victim's userId, meetingId, and an invalid authToken. This forces the victim to leave the conference, because the resulting verification failure is also observed and handled by the victim's client. The attacker must be a participant in any meeting on the server. This issue is patched in version 2.4.3. There are no workarounds."

Las versiones anteriores a la 2.4.3 est\u00e1n sujetas a una verificaci\u00f3n insuficiente de la autenticidad de los datos, lo que resulta en una Denegaci\u00f3n de Servicio (DoS). Un atacante puede realizar una llamada Meteor a \"validateAuthToken\" utilizando el ID de usuario, el ID de reuni\u00f3n y un token de autenticaci\u00f3n no v\u00e1lido de la v\u00edctima. Esto obliga a la v\u00edctima a abandonar la conferencia, porque el cliente de la v\u00edctima tambi\u00e9n observa y maneja el error de verificaci\u00f3n resultante. El atacante debe participar en cualquier reuni\u00f3n en el servidor. Este problema se solucion\u00f3 en la versi\u00f3n 2.4.3. No hay workaround."
