AI-analyzed exploit summary This repository contains a functional exploit for CVE-2019-1064, a local privilege escalation vulnerability in Windows AppXSVC. The exploit leverages a hardlink attack to manipulate file permissions and gain SYSTEM-level access to a target file.
Description
An elevation of privilege vulnerability exists when Windows AppX Deployment Service (AppXSVC) improperly handles hard links. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The security update addresses the vulnerability by correcting how Windows AppX Deployment Service handles hard links.
