This repository contains a proof-of-concept (PoC) exploit for CVE-2022-24924 (SVE-2021-24089), an improper access control vulnerability in the Samsung Live Wallpaper service on Windows. The exploit targets systems where the LiveWallpaperService is running (typically on Samsung laptops or where the app is installed from the Microsoft Store). The vulnerability arises because the service, running as SYSTEM, does not validate client connections over a named pipe, allowing an attacker to create a directory junction from a user-writable location to C:\Windows\System32. The PoC (poc.py) automates this process: it deletes the target user directory, creates a directory junction using external tools (CreateMountPoint.exe), writes a specific string to the named pipe to trigger the service, waits, and checks if a SYSTEM-privileged directory is created in System32. The exploit demonstrates local privilege escalation. The repository consists of a detailed README.md explaining the vulnerability and usage, and a single Python PoC script. No network endpoints are involved; all actions are local to the target system.
