CVE-2020-29042: An issue was discovered in BigBlueButton through 2.2.29.

Security readout for executives and security teams

BigBlueButton deployments through 2.2.29 may allow unlimited attempts against meeting access codes. If a meeting relies on a short or guessable code, an attacker could repeatedly try codes until one works, risking unauthorized meeting access. Exposure is most likely for internet-accessible BigBlueButton instances at or below 2.2.29 that use meeting access codes as a primary barrier. Treat this as a moderate access-control risk for organizations hosting confidential meetings. Prioritize internet-facing or externally used BigBlueButton servers, especially where meeting codes protect sensitive sessions. Mitigation focus: Inventory BigBlueButton instances and identify versions at or below 2.2.29.; Check BigBlueButton release notes and vendor guidance for the remediated supported version.; Do not rely on meeting access codes as the only protection for sensitive meetings..
