CVE-2026-4377
Dlink DWR-X1820 router uses weak default password generated from its IMEI number and does not require users to change it.
Does this matter?
Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.
Description
Dlink DWR-X1820 router uses weak default password generated from its IMEI number and does not require users to change it. An attacker who knows how passwords are generated can easily crack the default password if they have the device IMEI number. This issue was fixed in version 1.00B16CP.
