| CVE-2020-27605 | 1 Bigbluebutton | 1 Bigbluebutton | 2020-10-29 | 7.5 HIGH | 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-2020-12443 | 1 Bigbluebutton | 1 Bigbluebutton | 2020-05-06 | 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. | |||||
