Loading vulnerability…
An elevation of privilege vulnerability in the Microsoft XmlDocument class allows an attacker to escape the AppContainer sandbox when running in a browser context. The vulnerability affects multiple versions of Windows, including Windows 8.1, Windows 10, Windows RT 8.1, and various Windows Server editions. The flaw is related to improper enforcement of sandbox restrictions by the XmlDocument class, enabling privilege escalation.

This repository provides proof-of-concept (PoC) exploits for two Microsoft Edge vulnerabilities: CVE-2019-0555 (XmlDocument Insecure Sharing Elevation of Privilege) and CVE-2019-0567 (Edge Type Confusion). The structure includes three C++ files (BadgeUpdateManager.cpp, TileFlyoutUpdateManager.cpp, ToastNotificationManager.cpp) that demonstrate how to abuse Windows Runtime notification classes to expose the XmlDocument object across process boundaries. Each C++ PoC crafts an XML document with embedded XSLT and JScript, which, when processed, executes 'notepad.exe' via ActiveXObject, demonstrating code execution outside the Edge LPAC sandbox. The JavaScript files (ExecuteNotepad.js, TypeConfusion.js) provide utilities and a type confusion exploit to manipulate memory and object structures, facilitating the attack. The HTML file (tribell.html) serves as a UI to trigger the exploits. The README.md gives a detailed technical overview, affected versions, and references. The exploit is a POC and does not provide a weaponized or easily customizable payload, but it clearly demonstrates the sandbox escape and privilege escalation on vulnerable systems.
