Hikvision dvr password hack11/8/2022 #Hikvision dvr password hack android#We can only tell that both android apps have over a million installs.Īlso we have no way of knowing if this was hijacking of intended (admin or backdoor) behavior or a bug. Stykas added, If we change the password we can use the devices menu on the Hik-connect android app and manage the device (update firmware and brick it or do whatever we want) without any password given. How the Hikvision bug can be exploited Poking around to learn what could be done with Hik-connect and Ezviz, they determine the bug could be exploited to.Īfter that, even if the user tried factory resetting their device, it would not be unbound from the attackers account without contacting Hikvision. Stykas wrote, So now we can login as any user as long as we have his email, phone number or username (endpoint was also returning data for username although there was no UI for it) and impersonate him. They discovered that one of the features on Ezviz allowed then to mark a user as a friend with no interaction needed by the other user just by knowing the email or phone that the other user used upon registration. So what is Ezviz According to the about page, it is the consumer and residential-focused subsidiary of Hikvision, the worlds largest manufacturer of video surveillance solutions.Įzviz builds upon Hikvisions expertise and knowledge to bring robust, commercial-quality video products to consumers and the smart-home market. When he started playing around with his Hikvision DVR, he said it required a firmware update, which introduced the Hik-connect cloud service to help you access your camera without port forwarding on your router.Īfter hunting for a bug, Stykas and fellow tinker George Lavdanis ultimately discovered there was no validation on cookie values. It all started after Stykas saw a tweet on a really slow Friday. The researcher said “patched firmware is partially available though inconsistently deployed across various Hikvision firmware portals.If the vulnerability was exploited, it would allow attackers to access, manipulate and hijack other users devices.Īlso read: Severe flaws could turn your smart camera into someone elses surveillance tool. The vulnerability was reported to the vendor in June and an advisory announcing the availability of firmware patches was published on September 19. The issue impacts both older and newer Hikvision cameras and NVRs - a list of affected products has been made available. The Chinese company noted that exploitation is possible if the attacker has network access to the device or if the device is exposed to the internet. Hikvision described it as a command injection vulnerability - caused by insufficient input validation - that can be exploited using specially crafted messages. It will not be detectable by any logging on the camera itself.” “No username or password needed nor any actions need to be initiated by the camera owner. “Only access to the http(s) server port (typically 80/443) is needed,” the researcher added. “Given the deployment of these cameras at sensitive sites potentially even critical infrastructure is at risk,” the researcher warned. An attacker could also use compromised devices to access internal networks. #Hikvision dvr password hack full#The vulnerability can be exploited to gain root access and take full control of a device. The flaw, tracked as CVE-2021-36260, was discovered by a researcher who uses the online moniker “Watchful IP.” The researcher published a blog post over the weekend, but has not made public any technical details to prevent abuse. More than 70 Hikvision camera and NVR models are affected by a critical vulnerability that can allow hackers to remotely take control of devices without any user interaction.
