# Description
Hikvision IP Cameras Authentication Bypass (CVE-2017-7921)
Basically, hikvision cameras that are vulnerable to the CVE listed above, can have several routes exposed by using a simple base64 string supplied as an argument in the url.
For example:
`/System/configurationFile?auth=YWRtaW46MTEK`
This would allow an unauthenticated user to download the config file for the camera which includes user information. This configuration file uses weak encryption and a static key by default.
The python script supplied, will decrypt this configuration file.
I also supply a sample generated example configuration file for you to test.
# How To Use
`./decrypt_configurationFile.py <nameofdownloadedconfig>`
# Dependencies:
`sudo python3 -m pip install pycryptodome`
**Tested on Ubunut 20.04 with python 3.8.5**
