CVE-2024-3117Network attack vector

Authenticated dangerous-file upload via ChannelAction file parameter

Published Mar 31, 2024 · Updated Aug 15, 2024

Unrestricted file upload in YouDianCMS 9.5.0 through 9.5.12 allows remote authenticated users to upload dangerous files. The public record identifies the file parameter and ChannelAction.class.php but does not disclose the upload-processing logic or failed validation. Administrative privileges are required, and the established consequence is file placement rather than demonstrated code execution.
