Dahua IP Digicam Vulnerability May Let Attackers Take Full Management Over Gadgets


Particulars have been shared a couple of safety vulnerability in Dahua’s Open Community Video Interface Discussion board (ONVIF) commonplace implementation, which, when exploited, can result in seizing management of IP cameras.

Tracked as CVE-2022-30563 (CVSS rating: 7.4), the “vulnerability could possibly be abused by attackers to compromise community cameras by sniffing a earlier unencrypted ONVIF interplay and replaying the credentials in a brand new request in the direction of the digital camera,” Nozomi Networks stated in a Thursday report.

The problem, which was addressed in a patch launched on June 28, 2022, impacts the next merchandise –

  • Dahua ASI7XXX: Variations previous to v1.000.0000009.0.R.220620
  • Dahua IPC-HDBW2XXX: Variations previous to v2.820.0000000.48.R.220614
  • Dahua IPC-HX2XXX: Variations previous to v2.820.0000000.48.R.220614

ONVIF governs the event and use of an open commonplace for a way IP-based bodily safety merchandise reminiscent of video surveillance cameras and entry management programs can talk with each other in a vendor-agnostic method.


The bug recognized by Nozomi Networks resides in what’s referred to as the “WS-UsernameToken” authentication mechanism applied in sure IP cameras developed by Chinese language agency Dahua, permitting attackers to compromise the cameras by replaying the credentials.

In different phrases, profitable exploitation of the flaw may allow an adversary to covertly add a malicious administrator account and exploit it to acquire unrestricted entry to an affected system with the very best privileges, together with watching reside digital camera feeds.

All a risk actor must mount this assault is to have the ability to seize one unencrypted ONVIF request authenticated with the WS-UsernameToken schema, which is then used to ship a cast request with the identical authentication knowledge to trick the system into creating the admin account.

Dahua IP Camera Vulnerability

This disclosure follows the invention of comparable flaws in Reolink, ThroughTek, Annke, and Axis gadgets, underscoring the potential dangers posed by IoT safety digital camera programs given their deployment in essential infrastructure amenities.

“Risk actors, nation-state risk teams specifically, could possibly be all in favour of hacking IP cameras to assist collect intel on the tools or manufacturing processes of the goal firm,” the researchers stated.

“This info may support in reconnaissance performed previous to launching a cyberattack. With extra data of the goal atmosphere, risk actors may craft customized assaults that may bodily disrupt manufacturing processes in essential infrastructure.”


In a associated improvement, researchers from NCC Group documented 11 vulnerabilities impacting Nuki sensible lock merchandise that could possibly be weaponized to achieve arbitrary code execution and open doorways or trigger a denial-of-service (DoS) situation.

Additionally notable is an industrial management system (ICS) advisory issued by the U.S. Cybersecurity and Infrastructure Safety Company this week, warning of two critical safety flaws in MOXA NPort 5110 servers operating firmware model 2.10.

“Profitable exploitation of those vulnerabilities may permit an attacker to vary reminiscence values and/or trigger the system to grow to be unresponsive,” the company stated.
