1. Description
- Any registered user can login when edit cookie userInfo

2. Proof of Concept
- When login successful: DVR save cookie : userInfo + webport with 
value: base64 encode (user:pass)
Ex: http://dvr-domain.dynns.com:85 --> When login successful (user: 
admin, pass: admin), DVR will save cookie: userInfo85 with value 
YWRtaW46YWRtaW4= (admin:admin <-- base64 decode)
But Dvr not check pass with cookie. When not yet login, you add a 
cookie: userInfoXX (xx : web port) with value base64 encode (admin: any 
words). And go url: http://dvr-domain.dynns.com:XX/doc/page/main.asp. It 
will Authentication Bypass

3. Solution:
Update to Firmware version V3.0.0 build20170925
