The vulnerability has, however, been patched since 2017.
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.Īnd based on this, it's understandable that Vanguard nopes hard on it. 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. Any application running on the system (Windows), including sandboxed users, can issue an ioctl to this driver without any validation. In CPUID CPU-Z through 1.81, there are improper access rights to a kernel-mode driver (e.g., cpuz143_圆4.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. The CPU-Z driver had a vulnerability up to, and including, version 1.81, which was abused by hackers - both the cheating and the bank-account-stealing kinds.ĬVEDetails report followign on the vulnerability: MSI Afterburner, NZXT CAM and programs like them are often using it.
They are the makers of CPU-Z, the drivers of which are utilized in many other proprietary programs. If you want to know more about your computer, you should give this tool a try.If you don't know CPUID, you've probably still used their software, in one form or another. Overall, it’s a great useful tool that gathers more information about your computer than what most of us expect. The tool is built by the same guys in CPUID who also made the HWMonitor that we covered before. It also includes a validating process that allows to record your CPU-Z data within a database, which helps them to result in several statistics. You can export and save the results in TXT and HTML format as your reference in the future. The result comes out in one simple window with several tab at the top to switch. Simply launch the program and it starts gathering the information on its own and shows you the results in a few seconds. It also has the portable version in zip format that can be launched without first installing it, which may be more convenient and useful to most of the users. You can download the latest version of installation binary file from the website, and install it on your computer. CPU-Z is a freeware system tool that gathers information on some of the main devices of your computer system, such as CPU processor, Main Motherboard, Memory, Graphics, and Caches, based on the detection engine built upon CPUID System Information Development Kit.
