NMIS/BioDose V22.02 and previous versions rely on a common SQL Server user account to access data in the database. User access in the client application is restricted by a password authentication check in the client software but the underlying database connection always has access. The latest version of NMIS/BioDose introduces an option to use Windows user authentication with the database, which would restrict this database connection.
CVE-2026-3096 2026-09-18 N/A 4.7 MEDIUM
The product's web portals allow external links to be opened in a new browser tab. In certain configurations, the originating window retains access to the newly opened page, allowing interaction between the two browser contexts when navigating to external destinations. This vulnerability could allow an attacker to manipulate the original trusted application window after a user clicks a malicious external link. This manipulation can lead to users being redirected to phishing pages, enabling credential theft, or facilitating other unauthorized actions within the context of the trusted site.

CVE-2026-71187 2026-08-31 N/A 9.8 CRITICAL
The Ebyte device relies on client side authentication logic that can be reproduced by unauthenticated users. An attacker may generate valid authentication requests and bypass authentication to obtain administrative access to the device.
CVE-2026-76945 2026-08-31 N/A 7.5 HIGH
The affected Ebyte device relies on client-managed authentication tokens without sufficient server-side validation. An attacker may replay or manipulate authentication tokens to gain unauthorized access to administrative functionality.
CVE-2026-8830 1 Redhat 1 Build Of Keycloak 2026-07-23 N/A 4.3 MEDIUM
A flaw was found in Keycloak. An authenticated user can bypass configured WebAuthn policies during credential registration by manipulating client-side JavaScript. This occurs because the server-side processAction() fails to validate that the newly created credential's parameters, such as public key algorithms, match the realm's configured WebAuthn policies. This could lead to the creation of credentials that do not adhere to administrative security requirements, potentially weakening the overall security posture of the system by allowing non-compliant authentication methods.
CVE-2026-1363 2026-06-17 N/A 9.8 CRITICAL
IAQS and I6 developed by JNC has a Client-Side Enforcement of Server-Side Security vulnerability, allowing unauthenticated remote attackers to gain administrator privileges by manipulating the web front-end.
CVE-2025-30042 1 Cgm 1 Clininet 2026-06-17 N/A 7.8 HIGH
The CGM CLININET system provides smart card authentication; however, authentication is conducted locally on the client device, and, in reality, only the certificate number is used for access verification. As a result, possession of the certificate number alone is sufficient for authentication, regardless of the actual presence of the smart card or ownership of the private key.
CVE-2025-24517 2026-06-17 N/A 7.5 HIGH
