Arbitrary file upload via administrator avatars

Published Jul 15, 2024 · Updated Nov 22, 2024

Arbitrary file upload in Tmall_demo 2024.07.03 allows attackers to place unrestricted files through the administrator avatar feature. The upstream issue identifies the administrator avatar-upload path and states that it accepts any file, but its protected description does not disclose the handler or validation logic. Public records do not establish the authentication gate, storage location, web reachability, or whether an uploaded file can execute.
