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.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
