Summary

CVE-2025-61940 is a high-severity Use of Client-Side Authentication (CWE-603) vulnerability in Mirion Biodose\/Nmis. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-61940 is a vulnerability in NMIS/BioDose versions V22.02 and previous, stemming from the use of a common SQL Server user account with unrestricted database access. While the client application enforces user access restrictions via password authentication, the underlying database connection always uses this privileged account, bypassing client-side controls. Classified as CWE-603, it carries a CVSS v3.1 base score of 8.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L).

A low-privileged user (PR:L) with network access (AV:N) can exploit this issue with low attack complexity and no user interaction. The attacker leverages the privileged database connection to achieve high confidentiality impact through unauthorized data access, high integrity impact via data modification, and low availability impact.

The CISA ICS medical advisory (ICSMA-25-336-01) references mitigation via the latest NMIS/BioDose version, which introduces an option for Windows user authentication to restrict database connections based on user privileges.
