• Vulnerability Description:
User input passed through the “customicon” when creating a new course is not properly sanitized before being uploaded into the /content/ directory. This could be exploited to upload and execute arbitrary PHP code. Successful exploitation of this vulnerability should require an account with permissions to create new courses, however it could be exploited in conjunction with KIS-2015-06 in order to bypass the authentication mechanism.
