What is CVE-2025-30042?

The CGM CLININET system's smart card authentication has a critical flaw where the client device handles the authentication locally. This system relies solely on the certificate number for access verification, meaning that possession of this number alone allows unauthorized users to gain access, irrespective of whether they possess the smart card or the corresponding private key.

Affected Version(s)

CGM CLININET 0 < 2025.MS2
