CVE-2025-30042
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe CGM CLININET system's smart card authentication is fundamentally broken. Authentication occurs locally on the client device and only validates the certificate number, not the actual smart card or private key. This allows authentication bypass using only a certificate number without possessing the physical smart card or the corresponding private key.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed CGM Clininet versionLocate the CGM Clininet application in your system and check its version number (typically found in the application properties, about screen, or installed programs list)Affected if The version is lower than 2025.ms2 (for example, 2025.ms1, 2024.x, or earlier)
-
Determine if smart card authentication is configuredReview the CGM Clininet authentication settings or configuration files to verify whether smart card authentication has been enabled for user loginsAffected if Smart card authentication is enabled in the CGM Clininet configuration
-
Verify authentication validation locationExamine the authentication workflow or logs to determine whether certificate validation occurs locally on the client device or is performed server-sideAffected if Authentication validates only the certificate number locally without requiring server-side proof of private key possession (such as challenge-response verification)
You are affected if CGM Clininet version is below 2025.ms2 AND smart card authentication is enabled with client-side-only certificate number validation.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2025.ms2
Redesign the authentication to perform server-side validation of the actual smart card and private key, not just the certificate number. Implement proper cryptographic challenge-response verification that proves possession of the private key.
2025.ms2
- Verify current CGM CLININET version is below 2025.ms2
- Obtain the updated CGM CLININET version 2025.ms2 from official CGM vendor sources (www.cgm.com or authorized distributors)
- Apply the upgrade following vendor-provided installation instructions
- After upgrade, verify that authentication now properly validates smart card and private key presence rather than relying solely on certificate number
