This repository contains a single Metasploit module: 'Windows Escalate Service Permissions Local Privilege Escalation'. The module targets Windows systems and attempts to elevate privileges from administrator to SYSTEM by exploiting weak permissions in Windows services, their associated files, or registry keys. It can either create a new service or hijack an existing one if insecure permissions are detected. The module supports targeting a specific service or scanning all services for vulnerabilities, with an 'AGGRESSIVE' mode to exploit as many as possible. It specifically includes an exploit path for CVE-2025-21293, which involves registry permission abuse. The payload is a customizable Meterpreter EXE, written to a temporary directory and executed via service manipulation. The code is written in Ruby and is fully integrated into the Metasploit framework, making it weaponized and highly configurable. The main attack vector is local privilege escalation, and the module interacts with Windows service configuration files and registry keys as fingerprintable endpoints.
