CVE-2024-2406Network attack vector

Arbitrary file upload via Upload.php index

Published Mar 12, 2024 · Updated Aug 1, 2024

Unrestricted file upload in Gacjie Server 1.0 allows remote authenticated users to upload arbitrary files through the file parameter. The public record identifies the index function in /app/admin/controller/Upload.php as the locus but does not disclose which validation or storage operation accepts the crafted input. Low-privileged access is required, and the demonstrated consequence is placement of attacker-chosen files rather than disclosed code execution.
