Web file access

Files are increasingly served and received over HTTP: simple HTTP file servers and directory listings, WebDAV for read-write access, and managed file transfer products for business-to-business exchange. Each exposes its own surface, directory listing and traversal, upload-to-execution, authentication bypass, and the heavily-targeted MFT appliance vulnerabilities.

File sharing has moved onto HTTP, and three forms dominate. Simple HTTP file servers (from a language's built-in server to purpose-built apps) expose directories for download and sometimes upload. WebDAV extends HTTP with read-write verbs, turning a web server into a mountable, writable filesystem. And managed file transfer (MFT) products provide governed business-to-business file exchange through web portals and APIs. Each has a distinct surface: listing and traversal on plain file servers, upload-to-execution and verb abuse on WebDAV, and on MFT the authentication bypasses and injection flaws that have driven some of the largest mass-exploitation campaigns.

bash
# fingerprint what is serving files over HTTP
curl -sI http://<target>/                      # Server header, allowed methods
curl -s -X OPTIONS http://<target>/ -i | grep -i allow   # WebDAV verbs?
