Detailsinfo

A vulnerability was found in CPUID CPU-Z up to 1.81 (Chip Software) and classified as problematic. Affected by this issue is an unknown function of the component Kernel-Mode Driver. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality. CVE summarizes:

In CPUID CPU-Z through 1.81, there are improper access rights to a kernel-mode driver (e.g., cpuz143_x64.sys for version 1.43) that can result in information disclosure or elevation of privileges, because of an arbitrary read of any physical address via ioctl 0x9C402604. Any application running on the system (Windows), including sandboxed users, can issue an ioctl to this driver without any validation. Furthermore, the driver can map any physical page on the system and returns the allocated map page address to the user: that results in an information leak and EoP. NOTE: the vendor indicates that the arbitrary read itself is intentional behavior (for ACPI scan functionality); the security issue is the lack of an ACL.

The bug was discovered 10/16/2017. The weakness was published 10/16/2017 (Website). The advisory is available at github.com. This vulnerability is handled as CVE-2017-15302 since 10/14/2017.
