CPUID CPU-Z Arbitrary Read/Write Privilege Elevation Vulnerability

CPUID CPU-Z is a free software package for collecting information about system devices. A security vulnerability exists in versions of CPUID CPU-Z prior to 1.43, which originates from a program that can send ioctl 0x9C402430 calls to the kernel mode driver to exploit the vulnerability by writing ...

Information disclosure

In CPUID CPU-Z through 1.81, there are improper access rights to a kernel-mode driver e.g., cpuz143x64.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 t...

Code injection

In CPUID CPU-Z before 1.43, there is an arbitrary memory write that results directly in elevation of privileges, because any program running on the local machine while CPU-Z is running can issue an ioctl 0x9C402430 call to the kernel-mode driver e.g., cpuz141x64.sys for version 1.41...

CVE-2017-15302

In CPUID CPU-Z through 1.81, there are improper access rights to a kernel-mode driver e.g., cpuz143x64.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 t...

CVE-2017-15303

In CPUID CPU-Z before 1.43, there is an arbitrary memory write that results directly in elevation of privileges, because any program running on the local machine while CPU-Z is running can issue an ioctl 0x9C402430 call to the kernel-mode driver e.g., cpuz141x64.sys for version 1.41...

CVE-2017-15302

CVE-2017-15302 affects CPUID CPU-Z (Windows) up to version 1.81. The root cause is improper access rights to the kernel-mode driver (cpuz143_x64.sys) that allows an arbitrary read of any physical address via ioctl 0x9C402604 and the driver to map any physical page, returning the map page address ...

CVE-2017-15303

In CPUID CPU-Z before 1.43, there is an arbitrary memory write that results directly in elevation of privileges, because any program running on the local machine while CPU-Z is running can issue an ioctl 0x9C402430 call to the kernel-mode driver e.g., cpuz141x64.sys for version 1.41...

CVE-2017-15303

CVE-2017-15303 affects CPUID CPU-Z prior to 1.43. The flaw allows an arbitrary memory write via an ioctl 0x9C402430 to the kernel-mode driver (cpuz141_x64.sys for v1.41), enabling local elevation of privileges on the same host. This is a kernel-space write condition originating from userland inte...
