Remote file write via unrestricted upload
Published Aug 27, 2023 · Updated Aug 2, 2024
Unrestricted file upload in Bettershop LaikeTui allows remote attackers to write files through the user upload endpoint. The POST handler at index.php?module=api&action=user&m=upload accepts uploaded content without an enforced restriction, although the exact missing validation operation is undisclosed. Published evidence does not specify an authentication gate or establish code execution, so the demonstrated consequence is limited to writing attacker-chosen content.
