CyberRota Analysis
AI-GeneratedThe vulnerability affects PassMark PerformanceTest, BurnInTest, and OSForensics prior to specified builds, allowing local attackers to exploit hard-coded credentials in DirectIo64.sys to perform arbitrary physical memory writes. This can lead to unauthorized access and manipulation of system memory, potentially compromising system integrity and confidentiality. Organizations using these products should prioritize patching to mitigate the risk of local exploitation.

Original NVD Description
PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a hard-coded credentials vulnerability in DirectIo64.sys that allows local attackers to perform arbitrary physical memory writes by extracting an 8-byte key embedded as a hardcoded literal in the distributed binary and computing valid MD5 authentication tags for arbitrary IOCTL write requests. Attackers can additionally bypass a secondary validation gate by using the driver's own bit-clear IOCTL to clear a single bit in the gating instruction's displacement byte, causing all subsequent write requests to skip MAC verification, size checks, and Vendor ID checks entirely.
