| CVE-2020-27604 | 1 Bigbluebutton | 1 Bigbluebutton | 2024-11-21 | 4.0 MEDIUM | 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 | 5.0 MEDIUM | 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 | N/A | 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 | N/A | 3.5 LOW |

| 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 | 4.0 MEDIUM | 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 | 7.5 HIGH | 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 | 4.3 MEDIUM | 6.1 MEDIUM |

| BigBlueButton before 2.2.5 allows remote attackers to obtain sensitive files via Local File Inclusion. | |||||
