CVE-2022-23488

BigBlueButton is an open source web conferencing system. Versions prior to 2.4-rc-6 are vulnerable to Insertion of Sensitive Information Into Sent Data. The moderators-only webcams lock setting is not enforced on the backend, which allows an attacker to subscribe to viewers' webcams, even when the lock setting is applied. (The required streamId was being sent to all users even with lock setting applied). This issue is fixed in version 2.4-rc-6. There are no workarounds.

BigBlueButton es un sistema de conferencias web de código abierto. Las versiones anteriores a la 2.4-rc-6 son vulnerables a la inserción de información confidencial en los datos enviados. La configuración de bloqueo de cámaras web exclusivas para moderadores no se aplica en el backend, lo que permite a un atacante suscribirse a las cámaras web de los espectadores, incluso cuando se aplica la configuración de bloqueo. (El streamId requerido se enviaba a todos los usuarios incluso con la configuración de bloqueo aplicada). Este problema se solucionó en la versión 2.4-rc-6. No hay workaround.
