CVE-2025-64642 is an incorrect permission assignment vulnerability affecting Mirion Medical EC2 Software NMIS/BioDose V22.02 and earlier. The issue arises because installation directory paths are created with insecure default file permissions. In certain deployment scenarios, this allows users on client workstations to modify program executables and libraries located in the installation path. The weakness is classified as CWE-732 (Incorrect Permission Assignment for Critical Resource) and effectively exposes trusted application binaries to unauthorized local modification.
