The FlashUpload component in Korean GHBoard uses a client-side protection mechanism to prevent uploading of dangerous file extensions, which allows remote attackers to bypass restrictions and upload arbitrary files via a modified copy of component/flashupload/upload.html.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
