Upload Scanner

Summary: PortSwigger Research describes a Burp Suite extension, Upload Scanner, built to automate attacks against HTTP file uploads, including XSS, XXE, PHP/JSP/ASP code injection, and SSRF through m3u8 playlists parsed with LibAv. The extension is divided into modules by attack category, and its author is Tobias 'floyd' Ospelt of modzero AG, with version 1.0.8a last updated 21 February 2022.

What's compelling: The research argues file uploads are an underestimated testing area, since any server that parses files carries a much larger attack surface - and a REST XML service safe from XXE can still have an XXE issue in the image parser reading JPEG XMP metadata.
