CVE-2025-6204Known exploitationPublic exploitNetwork attack vector

Authenticated code execution via path-traversal file upload

Published Aug 4, 2025 · Updated Feb 26, 2026

Code injection in Dassault Systèmes DELMIA Apriso Release 2020 through Release 2025 allows remote authenticated users to execute arbitrary code. The UploadFile handler accepts traversal sequences in its filename parameter without canonicalizing the path, letting uploaded ASP content reach a web-served portal directory. Exploitation requires an authenticated account with upload access and executes the file in the web-server context.
