Overview
wwbn/avideo is an Audio and Video Platform or simply "A Video Platform".
Affected versions of this package are vulnerable to Arbitrary File Upload in the saveFile function. An authenticated user with manage permissions on a video can execute arbitrary code on the server by uploading a specially crafted file with a valid image MIME type but a dangerous extension, which is then saved in a web-accessible directory and executed by the server.
Note: This is only exploitable if the ImageGallery plugin is enabled.
