So in terms of permissions. What's the different between admin.youtube.comand a normal youtube user? I assume that the admin has a full permission set. If that's the case, that means it is a valid vulnerability for the reason being that the integrity of the service is impacted. The youtube user circumvents the design and gets arbitrary write (w) permissions of any file-type. (The access control matrix is bypassed here) Since YouTube by design is not an FTP Service, and even Google drive is a paid service - Then yes it is a vulnerability. Why are you guys looking for impact elsewhere? The impact is to the integrity of the service - arbitrary write permissions.

The only reasonable way to 'exploit' the bug is using youtube as a "personal storage" uploading non-video files to your own profile: sowhat? That would require a way to retrieve the stored data, which - as I understand - isn't possible here (although the report seems a bit hard-to-parse). From what I recall, you can just upload a blob of data and essentially see it disappear. We do have quite a few services where you can legitimately upload and share nearly-arbitrary content, though. Google Drive is a good example. /mz _______________________________________________ Full-Disclosure - We believe in it.
