CVE-2023-7181Network attack vector

Authenticated arbitrary file upload through attachment handler

Published Dec 30, 2023 · Updated Nov 20, 2024

Unrestricted file upload in DedeBIZ 6.2.0 through 6.2.12 allows remote authenticated users to write files through Add Attachment. The public record identifies the Add Attachment handler but does not disclose its file, function, request parameter, or failed validation operation. Administrative privileges are required, and the established consequence is placement of attacker-controlled files; server-side code execution is not established.
