The web interface on Dahua DHI-HCVR7216A-S3 devices with NVR Firmware 3.210.0001.10 2016-06-06, Camera Firmware 2.400.0000.28.R 2016-03-29, and SmartPSS Software 1.16.1 2017-01-19 allows remote attackers to obtain login access by leveraging knowledge of the MD5 Admin Hash without knowledge of the corresponding password, a different vulnerability than CVE-2013-6117.

An issue was discovered on Dahua DHI-HCVR7216A-S3 devices with NVR Firmware 3.210.0001.10 2016-06-06, Camera Firmware 2.400.0000.28.R 2016-03-29, and SmartPSS Software 1.16.1 2017-01-19. When SmartPSS Software is launched, while on the login screen, the software in the background automatically logs in as admin. This allows sniffing sensitive information identified in CVE-2017-6341 without prior knowledge of the password. This is a different vulnerability than CVE-2013-6117.

Dahua DVR 2.608.0000.0 and 2.608.GV00.0 allows remote attackers to bypass authentication and obtain sensitive information including user credentials, change user passwords, clear log files, and perform other actions via a request to TCP port 37777.

The authorization implementation on Dahua DVR appliances accepts a hash string representing the current date for the role of a master password, which makes it easier for remote attackers to obtain administrative access and change the administrator password via requests involving (1) ActiveX, (2) a standalone client, or (3) unspecified other vectors, a different vulnerability than CVE-2013-3612.

Dahua DVR appliances have a small value for the maximum password length, which makes it easier for remote attackers to obtain access via a brute-force attack.

Dahua DVR appliances use a password-hash algorithm with a short hash length, which makes it easier for context-dependent attackers to discover cleartext passwords via a brute-force attack.

Dahua DVR appliances have a hardcoded password for (1) the root account and (2) an unspecified "backdoor" account, which makes it easier for remote attackers to obtain administrative access via authorization requests involving (a) ActiveX, (b) a standalone client, or (c) unknown other vectors.

Dahua DVR appliances do not properly restrict UPnP requests, which makes it easier for remote attackers to obtain access via vectors involving a replay attack against the TELNET port.
