Summary
BigBlueButton Blind SSRF When Uploading Presentation (mitigation bypass)
Details

BigBlueButton is an open-source virtual classroom. BigBlueButton prior to versions 2.6.12 and 2.7.0-rc.1 is vulnerable to Server-Side Request Forgery (SSRF). This issue is a bypass of CVE-2023-33176. A patch in versions 2.6.12 and 2.7.0-rc.1 disabled follow redirect at httpclient.execute since the software no longer has to follow it when using finalUrl. There are no known workarounds. We recommend upgrading to a patched version of BigBlueButton.
