CVE-2026-4220Network attack vector

Unauthenticated file upload via SetWebpagePic.jsp parameters

Published Mar 16, 2026 · Updated Mar 16, 2026

Unrestricted file upload in Tiandy Easy7 Integrated Management Platform 7.17.0 allows remote attackers to place files via SetWebpagePic.jsp. The handler uses attacker-controlled targetPath and Suffix values to store an uploaded file without access-control or file-type restrictions. No authentication or user interaction is required, and the established consequence is arbitrary file placement rather than demonstrated code execution.
