Loading vulnerability…
CVE-2020-8950 is a privilege escalation vulnerability in the AUEPLauncher service of the Radeon AMD User Experience Program Launcher (through version 1.0.0.1) on Windows. The vulnerability arises from improper handling of files and symbolic links in the %PROGRAMDATA%\AMD\PPC\upload and %PROGRAMDATA%\AMD\PPC\temp directories. An attacker can place a crafted file in the upload directory and then create a symbolic link in the temp directory that points to an arbitrary folder and file name, allowing them to manipulate the service into performing privileged file operations on attacker-controlled locations.

This repository provides a local privilege escalation (LPE) exploit for AMD Radeon Software's User Experience Program Launcher (AUEPLauncher/AUEPMaster), targeting CVE-2020-8950. The exploit is implemented in Windows batch scripts and leverages a file write vulnerability and symbolic link manipulation to replace a privileged DLL (WindowsCoreDeviceInfo.dll) with a malicious one (evil.dll). The attacker must first identify a unique keyword in the 'send' folder, customize the exploit script accordingly, and execute it after a system reboot. The exploit writes the malicious DLL to a writable directory, creates a symbolic link to the system DLL, and triggers the vulnerable process to load the attacker's DLL, resulting in a SYSTEM shell. The repository includes both the main exploit and an older version, as well as detailed usage notes. Multiple fingerprintable file paths are involved, primarily under 'C:\ProgramData\AMD\PPC\' and 'C:\windows\system32\'. The exploit is operational and requires some manual steps for successful execution.
