CVE-2026-76174Network attack vector

Code execution via filename-only CSV upload validation

Published Sep 3, 2026 · Updated Sep 3, 2026

Unrestricted file upload in OCS Inventory NG 2.12.6 allows remote authenticated users to execute code through its Ocsreports web console. The admin_info CSV upload trusts the client-supplied filename instead of checking content or restricting dangerous types, placing PHP in a web-accessible directory. Administrator privileges and subsequent server-side processing of the uploaded file are required; code runs with the web service account.
