PassMark Software PerformanceTest
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PassMark PerformanceTest 11.1 build 1012 之前、BurnInTest 11.1 build 1000 之前，以及 OSForensics 11.1 build 1016 之前的版本中，其 DirectIo64.sys 内核驱动程序存在一个不当访问控制漏洞。该漏洞允许未授权的本地用户通过打开一个未设置安全描述符而创建的设备对象句柄，从而执行特权硬件操作。攻击者可以通过应用于该设备的宽松默认 Windows ACL，发送 IOCTL 来访问受限的硬件操作，而不受权限或完整性级别的

Vulnerability Title
PassMark PerformanceTest, BurnInTest, and OSForensics Improper Access Control via DirectIo64.sys
Source: CVE Program / CVE List V5
Vulnerability Description
PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an improper access control vulnerability in the DirectIo64.sys kernel driver that allows unprivileged local users to perform privileged hardware operations by opening a handle to the device object created without a security descriptor. Attackers can issue IOCTLs through the permissive default Windows ACL applied to the device to access restricted hardware operations regardless of privilege or integrity level.
