CVE-2024-33786Public exploitNetwork attack vector

Unauthenticated code execution via unrestricted ASP upload

Published May 3, 2024 · Updated Aug 2, 2024

Unrestricted file upload in Zhongcheng Kexin Ticketing Management Platform 20.04 allows remote attackers to execute arbitrary code. The unauthenticated /SystemManager/Introduction.ashx endpoint accepts a multipart file whose fileName field supplies an .asp name, then stores it in a web-accessible location without blocking executable content. No credentials or user interaction are required; requesting the returned path executes the uploaded ASP code with the server's privileges.
