The affected product is a consumer wireless router. Routers are designed to be deployed at the network edge, and their management interfaces, particularly those intended for remote administration, are frequently exposed to the internet, either intentionally or through default configurations.

Horizon Alert

Summary of the vulnerability and why it matters

The D-Link DIR-610 devices contain a flaw that allows unauthorized remote command execution. This vulnerability stems from the handling of the 'cmd' parameter within the 'command.php' file. Exploiting this could lead to significant business disruption and data compromise.

  • Vulnerable D-Link DIR-610 devices
  • Remote command execution flaw
  • Significant business risk and data impact

Attack Path

How an attacker could exploit the issue

This vulnerability allows an attacker to execute commands on a vulnerable D-Link DIR-610 device. The attack targets the command.php script, specifically exploiting the 'cmd' parameter. Successful exploitation could allow an attacker to gain control over the affected device and potentially access or manipulate data. Organizations using these devices should be aware of the potential for unauthorized command execution.

  • Network access to device
  • Authenticated attacker sends crafted command
  • Remote command execution occurs

Live Threat

Current exploitation, exposure, and threat context

The identified vulnerability in D-Link DIR-610 devices could allow for remote command execution. This means an attacker could potentially execute arbitrary commands on the affected device. The vulnerability affects products that are no longer supported by the manufacturer, indicating a lack of security updates. Organizations using these devices face significant business risk due to the potential for unauthorized system access and control.

  • Attackers with low skill could exploit it.
  • Network access and limited privileges are required.
  • Business risk is high due to unsupported products.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability affects D-Link DIR-610 devices due to a remote command execution flaw. The affected products are no longer supported by the maintainer. Organizations using these devices face significant business risk if they remain in operation.

Frequently asked questions

What is the D-Link DIR-610 and what is it used for?

The D-Link DIR-610 is a consumer wireless router. It is used to provide network connectivity for devices in a home or small office environment, allowing them to access the internet and communicate with each other.

What is CVE-2020-9377 and what type of weakness does it represent?

CVE-2020-9377 is a vulnerability in D-Link DIR-610 devices that allows remote command execution. This is classified as a CWE-78 weakness, which refers to the failure to properly neutralize special elements in a user-supplied input before that input is used in an operating system command.

How can an attacker exploit the D-Link DIR-610 vulnerability?

An attacker can exploit this vulnerability by sending a specially crafted command through the 'cmd' parameter to the 'command.php' file on the device. This specific vulnerability does not require a user to interact with a malicious link or file to be triggered.

Who should be concerned about the D-Link DIR-610 vulnerability?

Anyone using D-Link DIR-610 devices should be concerned. These devices are typically internet-facing as routers, meaning they are exposed to potential threats from outside the network.

What is the first step for someone running D-Link DIR-610 devices?

The first step is to identify all D-Link DIR-610 devices currently in use. Since these products are no longer supported by the manufacturer, they should be disconnected from the network and replaced with maintained alternatives to mitigate risk.
