In affected versions are affected by a Server-Side Request Forgery (SSRF) vulnerability. In an `insertDocument` API request the user is able to supply a URL from which the presentation should be downloaded. This URL was being used without having been successfully validated first. An update to the `followRedirect` method in the `PresentationUrlDownloadService` has been made to validate all URLs to be used for presentation download. Two new properties `presentationDownloadSupportedProtocols` and `presentationDownloadBlockedHosts` have also been added to `bigbluebutton.properties` to allow administrators to define what protocols a URL must use and to explicitly define hosts that a presentation cannot be downloaded from. All URLs passed to `insertDocument` must conform to the requirements of the two previously mentioned properties. Additionally, these URLs must resolve to valid addresses, and these addresses must not be local or loopback addresses. There are no workarounds. Users are advised to upgrade to a patched version of BigBlueButton.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/65533"}, {"timestamp": "2023-07-05T17:49:00Z", "date_only": false, "value": "2023-07-05T17:49Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2023-33176", "record": "GSD-2023-33176", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-10-31T01:20:33Z", "date_only": false, "value": "2023-10-31T01:20:33.000000Z", "kind": "sighting", "label": "Seen", "source": "https://t.me/cibsecurity/73198", "record": "CVE-2023-33176", "field": "creation_timestamp", "uuid": "9885cc14-f75c-406f-9ab1-c90108b7d422", "content": "\u203c CVE-2023-43798 \u203c\n\nBigBlueButton 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.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/73198"}, {"timestamp": "2023-12-13T01:20:36.489Z", "date_only": false, "value": "2023-12-13T01:20:36.489475Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-33176", "record": "GSD-2023-33176", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-02T15:39:35.770Z", "date_only": false, "value": "2024-08-02T15:39:35.770Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2023-33176", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-08-15T17:53:05.443Z", "date_only": false, "value": "2024-08-15T17:53:05.443+00:00", "kind": "other", "label": "Document generated", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-1568", "record": "WID-SEC-W-2023-1568", "field": "document.tracking.generator.date"}, {"timestamp": "2024-11-12T15:18:33.796Z", "date_only": false, "value": "2024-11-12T15:18:33.796074Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-33176", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2024-11-12T15:18:33.796Z", "date_only": false, "value": "2024-11-12T15:18:33.796074Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-33176", "record": "FKIE_CVE-2023-33176", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2024-11-12T15:18:46.803Z", "date_only": false, "value": "2024-11-12T15:18:46.803Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2023-33176", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-11-12T15:18:46.803Z", "date_only": false, "value": "2024-11-12T15:18:46.803Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-33176", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T06:01:14.283Z", "date_only": false, "value": "2026-06-17T06:01:14.283", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-33176", "record": "FKIE_CVE-2023-33176", "field": "lastModified"}]}
