BigBlueButton is an open source web conferencing system. This vulnerability only affects release candidates of BigBlueButton 2.4. The attacker can start a subscription for poll results before starting an anonymous poll, and use this subscription to see individual responses in the anonymous poll. The attacker had to be a meeting presenter. This issue is patched in version 2.4.0. There are no workarounds.
Add your gear to cvedb and we'll alert you only when bigbluebutton ships something exploited.
