Vulnerability Note VU#899080

Zhuhai Raysharp firmware for DVRs from multiple vendors contains hard-coded credentials

Original Release date: 17 Feb 2016 | Last revised: 19 Feb 2016

Overview

Digital Video Recorders (DVRs), security cameras, and possibly other devices from multiple vendors use a firmware derived from Zhuhai RaySharp that contains a hard-coded root password.

Description

CWE-259: Use of Hard-coded Password - CVE-2015-8286

According to the reporter, DVR devices based on the Zhuhai RaySharp firmware contain a hard-coded root password. Remote attackers with knowledge of the password may gain root access to the device.

Furthermore, it was previously reported publicly that many of these devices enable remote access via telnet or port 9000 by default.

The CERT/CC has not been able to confirm this information directly with Zhuhai RaySharp. The Vendor List below provides more information on each manufacturer that was reported to be vulnerable.

The reporter, Risk Based Security, has provided security advisory RBS-2016-001 with more information.

Impact

An unauthenticated remote attacker may gain root access to the device.

Solution

Apply an update if possible

Some vendors have released updated firmware to address this issue. Please contact your device manufacturer for more information. The Vendor List below provides more information on each manufacturer that was reported to be vulnerable.

If your vendor does not have an updated firmware available at this time, you may consider the following mitigations:

Restrict network access

Use a firewall or similar technology to restrict access to trusted hosts, networks, and services.
