# Exploit Title: Iperius Remote 1.7.0 Unquoted Service Path Elevation of Privilege # Date: 26/09/2016 # Exploit Author: Tulpa # Contact: tulpa@tulpa-security.com # Author website: www.tulpa-security.com # Vendor Homepage: http://www.iperiusremote.com # Software Link: https://www.iperiusremote.com/download.aspx # Version: Software Version 1.7.0 # Tested on: Windows 7 x86 # Shout-out to carbonated and ozzie_offsec 1. Description: Iperius Remote allows the user to install the application as a service with an unquoted service path running with SYSTEM privileges. It is important to note that the application installs itself as a service in the same location where the setup file in ran from. Provided that the end user initiates the installation from a directory with spaces in it's path, this could allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. 2.

Exploit: A successful attempt would require the local user to be able to insert their code in the system path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user's code would execute with the elevated privileges of the application. |
