Dahuasecurity: >> Dvr3204lf-Al Security Vulnerabilities
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.
