Authenticated arbitrary file upload via unchecked file argument
Published Mar 2, 2025 · Updated Mar 3, 2025
Unrestricted file upload in ZfileAction.upload in 株式会社ジーティーアイ Z平台 2024-8 allows remote authenticated users to write arbitrary files. The handler accepts the attacker-controlled file argument without enforcing restrictions on dangerous file types; further validation details are undisclosed. Low-privileged access to the network endpoint is required, and the demonstrated consequence is file placement rather than confirmed code execution.
