Privilege-Escalation Vulnerability

March 15, 2017

Dear Valued Customers and Partners:

Hikvision became aware of a privilege-escalation vulnerability that could potentially present a cybersecurity concern under certain, fairly uncommon circumstances. With this announcement, Hikvision would like to notify you that our R&D team has determined that a firmware update will be required to resolve this issue. The issue is resolved once the device is upgraded to the latest firmware.

What is the privilege-escalation vulnerability?

When a specific request code is used to access the IP cameras with particular firmware versions directly, it may allow attackers to obtain an unauthorized escalated additional user privilege to acquire or tamper with the device information.

Which Hikvision products could be affected and how are those cameras accessed?

This code error only affects the Hikvision IP cameras listed in the attached “Security Notification: Privilege-Escalation Vulnerability in Certain Hikvision IP Cameras.”

The overwhelming majority of Hikvision cameras are accessed through aconnected NVR, Hikvision iVMS software, or third-party VMS software. As such, it limits the possibility for Hikvision IP cameras to be open to public access, lowering the risk of the cybersecurity exposure. To date, Hikvision is not aware of any reports of malicious activity associated with this vulnerability.


How is Hikvision resolving this issue?

In the interest of protecting our customers from any potential cybersecurity threat, Hikvision is taking proactive action to make you aware of this issue, and to inform you of the firmware upgrade, readily available now, that resolves this issue.

What should users of these particular cameras do?

Hikvision is advising all users of these cameras to upgrade to the correct firmware version, which fixes this issue. Please note, for the Affected Versions' firmware listed in the table below, you may need a two-step upgrade process. We've packed all necessary firmware and a README text file into a single download file. Please follow the README instruction to upgrade your device's firmware. If you're still using HiDDNS service directly connected to your IP camera, please use v5.4.41 (v5.4.71 for DF series PTZ), which is packed in the download file. Starting with v5.4.5 (v5.4.9 for DF series PTZ) HiDDNS service is no longer supported, but only Hik-Connect is available.

Please refer to the table below.
