CVE-2021-27579

Estado: ModificadaAlta (7.8)—

Snow Inventory Agent through 6.7.0 on Windows uses CPUID to report on processor types and versions that may be deployed and in use across an IT environment. A privilege-escalation vulnerability exists if CPUID is enabled, and thus it should be disabled via configuration settings.
