This repository contains a single Metasploit module targeting a local privilege escalation vulnerability (CVE-2019-15742) in Plantronics Hub for Windows. The exploit abuses the SpokesUpdateService.exe, which runs as SYSTEM and executes a file specified in a user-writable configuration file (MajorUpgrade.config). The module checks for the presence of the vulnerable service and directory, writes a custom payload executable to a writable directory (default: %TEMP%), and overwrites the MajorUpgrade.config file to point to the payload. When the service processes the config, it executes the payload as SYSTEM, granting the attacker elevated privileges. The module is written in Ruby, follows standard Metasploit conventions, and is operational with a default payload of windows/meterpreter/reverse_tcp, but can be customized. The only file in the repository is the exploit module itself.
