{"id":"CVE-2022-29236","state":"PUBLISHED","title":"Improper access control for pencil annotations in BigBlueButton","description":"BigBlueButton is an open source web conferencing system. Starting in version 2.2 and prior to versions 2.3.18 and 2.4-rc-6, an attacker can circumvent access restrictions for drawing on the whiteboard. The permission check is inadvertently skipped on the server, due to a previously introduced grace period. The attacker must be a meeting participant. The problem has been patched in versions 2.3.18 and 2.4-rc-6. There are currently no known workarounds.","publishedAt":"2022-06-01T23:25:12.000Z","updatedAt":"2024-08-03T06:17:54.254Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["bigbluebutton bigbluebutton"],"affected":[{"vendor":"bigbluebutton","product":"bigbluebutton","versions":[{"version":">= 2.2, < 2.3.18","status":"affected"},{"version":">= 2.4-alpha-1, < 2.4-rc-6","status":"affected"}]}],"references":["https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-p93g-r9gm-9v6r","https://github.com/bigbluebutton/bigbluebutton/pull/13803","https://github.com/bigbluebutton/bigbluebutton/pull/14265","https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.3.18","https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.4-rc-6"],"weaknesses":["CWE-285"],"ingestedAt":"2026-10-29T19:49:57.813Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/29xxx/CVE-2022-29236.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-29236","state":"PUBLISHED","datePublished":"2022-06-01T23:25:12.000Z","dateUpdated":"2024-08-03T06:17:54.254Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-04-13T00:00:00.000Z"},"containers":{"cna":{"title":"Improper access control for pencil annotations in BigBlueButton","descriptions":[{"lang":"en","value":"BigBlueButton is an open source web conferencing system.
