CVE-2025-64298

Sensitive file access via insecure Windows share

Published Dec 2, 2025 · Updated Dec 9, 2025

Incorrect permissions in Mirion Medical BioDose/NMIS before 23.0 allow local users to access sensitive database and configuration files. In networked installations using embedded Microsoft SQL Server Express, default Windows-share directory paths expose those files to client workstations. Access requires the affected networked configuration and permits disclosure, alteration, or interruption of the exposed files without prior privileges.
