Ioctlance - A Tool That Is Used To Hunt Vulnerabilities In X64 WDM Drivers - Hacking Land

Description

Presented at CODE BLUE 2023, this project titled Enhanced Vulnerability Hunting in WDM Drivers with Symbolic Execution and Taint Analysis introduces IOCTLance, a tool that enhances its capacity to detect various vulnerability types in Windows Driver Model (WDM) drivers. In a comprehensive evaluation involving 104 known vulnerable WDM drivers and 328 unknow n ones, IOCTLance successfully unveiled 117 previously unidentified vulnerabilities within 26 distinct drivers. As a result, 41 CVEs were reported, encompassing 25 cases of denial of service, 5 instances of insufficient access control, and 11 examples of elevation of privilege.
