Loading vulnerability…
CVE-2022-25479 is a vulnerability in the Realtek RtsPer (PCIe Card Reader) driver (RtsPer.sys) before version 10.0.22000.21355 and the Realtek RtsUer (USB Card Reader) driver (RtsUer.sys) before version 10.0.22000.31274. The vulnerability allows for the leakage of uninitialized kernel memory from both the stack and the heap to user space, potentially exposing sensitive information.

This repository contains a local privilege escalation exploit targeting a Realtek driver vulnerability on Windows, chaining CVE-2024-40431 and CVE-2022-25479. The main exploit file, 'exploit_driver_realtek.c', is a C program that interacts directly with the vulnerable driver using IOCTL codes to read and write kernel memory. The exploit leaks kernel addresses, locates the base of the ntoskrnl.exe, and manipulates the SeDebugPrivilege in kernel memory to elevate privileges. It then locates the 'winlogon.exe' process, opens it with full access, and spawns a SYSTEM-level command shell ('cmd.exe'). The exploit demonstrates a data-only attack for EOP, requiring local access and the presence of the vulnerable driver. The repository is operational, providing a working exploit with a hardcoded payload, and is not part of a larger framework. The only fingerprintable endpoints are the use of 'winlogon.exe' and spawning 'C:\Windows\system32\cmd.exe'.
