Loading vulnerability…
An information disclosure vulnerability exists in the Windows kernel due to improper handling of objects in memory. An attacker must log on to the affected system and execute a specially crafted application to exploit this flaw. The vulnerability does not allow direct code execution or privilege escalation, but may expose sensitive information that could be leveraged in further attacks.

This repository provides a proof-of-concept (PoC) exploit for CVE-2020-16938, a vulnerability in certain Windows 10 Insider Preview builds that allows an unprivileged user to bypass NTFS permissions and read the entire disk. The main exploit is implemented in C++ (ntfs_bypass/ntfs_bypass/ntfs_bypass.cpp) and leverages Windows Native API calls to enumerate device objects under the \Global?? namespace, identify SCSI disk symlinks, and open raw disk device handles for reading. The exploit requires the user to select a disk device, after which it attempts to open the device for unrestricted reading. The README and PoC notes confirm the exploit's effectiveness on Windows 10 Insider builds 19587.1000 and 19619. The repository is structured as a Visual Studio C++ project, with the main logic in ntfs_bypass.cpp and supporting code in wrapper.hpp. The exploit is local-only and does not require network access. No weaponized payload is included; the exploit simply demonstrates the permission bypass and disk dumping capability.
