Unauthenticated file disclosure via path traversal
Published Feb 14, 2024 · Updated Aug 13, 2024
Path traversal in Sharp Cloud-based Energy Controller firmware B0.1.9.1 and earlier allows attackers to read arbitrary files. Sharp has not published the affected request handler, pathname field, or the operation that permits traversal outside its intended directory. Exploitation requires unauthenticated access from the same network and is limited to disclosure of file contents on the controller.
