CVE-2024-39302Network attack vector

Privilege escalation via permissive Resque directory

Published Jun 28, 2024 · Updated Aug 2, 2024

Improper privilege management in BigBlueButton affected releases allows attackers to escalate privileges through a server installation. The bbb-record-core package installs the bundled Resque 2.6.0 directory under /usr/local/bigbluebutton/core with overly elevated file permissions rather than restricting access. The advisory does not disclose how attackers reach or use the server-side directory, so the precise execution path remains unspecified.
