An authenticated arbitrary file upload vulnerability in the Courses/Work Assignments module of gunet Open eClass v3.11, and fixed in v3.13, allows attackers to execute arbitrary code via uploading a crafted SVG file.

The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, an arbitrary file upload vulnerability in the theme import functionality enables an attacker with administrative privileges to upload arbitrary files on the server's file system. The main cause of the issue is that no validation or sanitization of the file's present inside the zip archive. This leads to remote code execution on the web server. Version 4.2 patches the issue.

The Open eClass platform (formerly known as GUnet eClass) is a complete Course Management System. An arbitrary file upload vulnerability in the "save" functionality of the H5P module enables unauthenticated users to upload arbitrary files on the server's filesystem. This may lead in unrestricted RCE on the backend server, since the upload location is accessible from the internet. This vulnerability is fixed in 3.16.

Cross-site scripting (XSS) vulnerability in GUnet OpenEclass E-learning Platform version 3.15 and before allows a authenticated privileged attacker to execute arbitrary code via the title and description fields of the badge template editing function.

File Upload vulnerability in openeclass v.3.15 and before allows an attacker to execute arbitrary code via a crafted file to the certbadge.php endpoint.

Unrestricted File Upload vulnerability in Greek Universities Network Open eClass v.3.15 and earlier allows attackers to run arbitrary code via upload of crafted file to certbadge.php endpoint.

An issue in the jmpath variable in /modules/mindmap/index.php of GUnet Open eClass Platform (aka openeclass) v3.12.4 and below allows attackers to read arbitrary files via a directory traversal.

Multiple Cross-Site Scripting (XSS) were discovered in 'openeclass Release3.5.4'. The vulnerabilities exist due to insufficient filtration of user-supplied data (meetingid, user) passed to the 'openeclass-master/modules/tc/webconf/webconf.php' URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.
