CVE-2025-12867Network attack vector

Administrator code execution via unrestricted PHP upload

Published Nov 10, 2025 · Updated Nov 10, 2025

Arbitrary file upload in Hundred Plus EIP Plus before RELEASE_240626 allows remote authenticated users to execute PHP code on the server. An administrator-only function accepts specially crafted network packets without restricting dangerous PHP content, but its endpoint and validation logic are undisclosed. Administrator privileges are required; successful exploitation installs a web shell that enables arbitrary server-side code execution and compromise of application data and availability.
