CVE-2024-42676Public exploitNetwork attack vector

Authenticated code execution via unrestricted ASPX upload

Published Aug 15, 2024 · Updated Nov 18, 2024

Unrestricted file upload in Huizhi Enterprise Resource Management System 1.0 and earlier allows remote authenticated users to execute arbitrary code. The /nssys/common/Upload.Aspx endpoint's DNPageAjaxPostBack action accepts a dangerous server-executable upload without enforcing a safe file-type restriction. A low-privileged authenticated session is required; an uploaded ASPX payload executes with the web application's server-side privileges.
