CVE-2020-27609 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 5.3 Medium
BigBlueButton through 2.2.28 records a video meeting despite the deactivation of video recording in the user interface. This may result in data storage beyond what is authorized for a specific meeting topic or participant.
CVE-2020-27608 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 6.1 Medium
In BigBlueButton before 2.2.28 (or earlier), uploaded presentations are sent to clients without a Content-Type header, which allows XSS, as demonstrated by a .png file extension for an HTML document.
CVE-2020-27607 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 6.5 Medium
In BigBlueButton before 2.2.28 (or earlier), the client-side Mute button only signifies that the server should stop accepting audio data from the client. It does not directly configure the client to stop sending audio data to the server, and thus a modified server could store the audio data and/or transmit it to one or more meeting participants or other third parties.
CVE-2020-27606 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 5.3 Medium
BigBlueButton before 2.2.28 (or earlier) does not set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.
CVE-2020-27605 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 9.8 Critical
BigBlueButton through 2.2.28 uses Ghostscript for processing of uploaded EPS documents, and consequently may be subject to attacks related to a "schwache Sandbox."
CVE-2020-27604 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 6.5 Medium
BigBlueButton before 2.3 does not implement LibreOffice sandboxing. This might make it easier for remote authenticated users to read the API shared secret in the bigbluebutton.properties file. With the API shared secret, an attacker can (for example) use api/join to join an arbitrary meeting regardless of its guestPolicy setting.
CVE-2020-27603 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 7.5 High
BigBlueButton before 2.2.27 has an unsafe JODConverter setting in which LibreOffice document conversions can access external files.
CVE-2020-27602 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 9.8 Critical
BigBlueButton before 2.2.7 does not have a protection mechanism for separator injection in meetingId, userId, and authToken.
CVE-2020-27601 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 3.5 Low
In BigBlueButton before 2.2.7, lockSettingsProps.disablePrivateChat does not apply to already opened chats. This occurs in bigbluebutton-html5/imports/ui/components/chat/service.js.
CVE-2020-26163 1 Bigbluebutton 1 Greenlight 2024-11-21 8.8 High
BigBlueButton Greenlight before 2.5.6 allows HTTP header (Host and Origin) attacks, which can result in Account Takeover if a victim follows a spoofed password-reset link.
CVE-2020-25820 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 6.5 Medium
BigBlueButton before 2.2.7 allows remote authenticated users to read local files and conduct SSRF attacks via an uploaded Office document that has a crafted URL in an ODF xlink field.
CVE-2020-12443 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 9.8 Critical
BigBlueButton before 2.2.6 allows remote attackers to read arbitrary files because the presfilename (lowercase) value can be a .pdf filename while the presFilename (mixed case) value has a ../ sequence. This can be leveraged for privilege escalation via a directory traversal to bigbluebutton.properties. NOTE: this issue exists because of an ineffective mitigation to CVE-2020-12112 in which there was an attempted fix within an NGINX configuration file, without considering that the relevant part of NGINX is case-insensitive.
CVE-2020-12113 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 6.1 Medium
BigBlueButton before 2.2.4 allows XSS via closed captions because dangerouslySetInnerHTML in React is used.
CVE-2020-12112 1 Bigbluebutton 1 Bigbluebutton 2024-11-21 7.5 High
BigBlueButton before 2.2.5 allows remote attackers to obtain sensitive files via Local File Inclusion.
