Overview
On October 10, 2023, D-Link became aware of 3rd Party security blog BleepingComputer disclosure of a new Mirai Botnet Variant called IZ1H9. This new Mirai variant targets many consumer products from various vendors, including Legacy EOL/EOS D-Link products. The referenced vulnerabilities for D-Link products are CVE-2015-1187, CVE-2016-20017, CVE-2020-25506, and CVE-2021-45382.
These CVE-ID vulnerabilities affect legacy D-Link Routers and IOT devices that have reached their End of Life ("EOL")/End of Service Life ("EOS") Cycle. Products that have come their EOL/EOS no longer receive device software updates and security patches and are no longer supported by D-Link US (D-Link Systems, Inc.).
D-Link US recommends that D-Link devices that have reached EOL/EOS be retired and replaced. Please get in touch with your regional office for recommendations (LINK).
We have listed the CVE-id's and which products are affected. The last known archive of information on these products is at https://legacy.us.dlink.com.
Some products have fixes for these older CVEs, but D-Link US must encourage owners of the affected product list to retire and replace them.
Below, you will find an offer to best offer discounted prices to current new products under support and receive security updates. We recommend securing upgrades as soon as you know your product is affected.
Regardless of product type or US sales channel, D-Link's general policy is that when products reach EOS/EOL, they can no longer be supported, and all firmware development for these products ceases. Please read the information and recommendations below.

Recommendation for End-of-Support/End-of-Life Products
From time to time, D-Link will decide that some of its products have reached End of Support ("EOS") / End of Life (“EOL”). D-Link may choose to EOS/EOL an effect due to the evolution of technology, market demands, new innovations, product efficiencies based on new technologies, or the product matures over time and should be replaced by functionally superior technology.
For US Consumer
If a product has reached End of Support ("EOS") / End of Life ("EOL"), there is normally no further extended support or development for it.
Typically for these products, D-Link will be unable to resolve device or firmware issues since all development and customer support has ceased.
D-Link US is prohibited to provide support for these EOL/EOS products, if you are outside the US, please contact your regional D-Link office. If your device was provided by licensed carrier (service provider) and firmware, please contact your carrier (service provider). May devices on this list have available 3rd party open-firmware, D-Link does not support open-firmware which voids any warranty and is solely the responsibility of the device's owner.
D-Link strongly recommends that this product be retired and cautions that any further use of this product may be a risk to devices connected to it. If US consumers use these devices against D-Link's recommendation, please make sure the device has the last know firmware which can be located on the Legacy Website links above. Please frequently update the device's unique password to access its web-configuration, and always have WIFI encryption enabled with a unique password. Web configuration
