This repository contains a working local privilege escalation exploit for CVE-2023-7261, targeting the Google Chrome Updater on Windows. The exploit is implemented in C++ (CVE-2023-7261.cpp) and leverages a symbolic link (DOS device redirection) and named pipe to manipulate the Chrome Updater's update mechanism. By exploiting this flaw, a local attacker can escalate privileges and spawn a SYSTEM-level command shell (cmd.exe). The exploit checks for access to the 'SYSTEM\CurrentControlSet\Services\Fax' registry key, creates and interacts with a named pipe (\\.\Pipe\mypipe), and uses temporary directories (such as C:\Users\Public\test) as part of its operation. The README.md provides a high-level description and references for further details. The exploit is operational and provides a SYSTEM shell if successful.
