Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify device model is D-Link DIR-820LInspect the device label on the physical hardware, or check the model number displayed in the device web management interface under Status or System Information.Affected if The device is not a D-Link DIR-820L unit.
-
Check firmware version installedAccess the router web interface, navigate to Status or System Settings, and locate the firmware version field. Alternatively, check the firmware file name if you have access to the device filesystem or backup.Affected if The installed firmware version cannot be determined or differs from the labeled version.
-
Compare installed version to affected rangeCompare the firmware version you found in step 2 against the affected version: 1.05B03. The vulnerability affects only this exact version.Affected if The installed firmware version is exactly 1.05B03.
-
Assess remote management exposureIn the router web interface, check the Remote Management or Web Management settings (typically under Setup or Advanced). Determine if remote administration is enabled and accessible from the WAN interface.Affected if Remote management is enabled and the device is accessible from the internet or untrusted networks.
You are affected if you have a D-Link DIR-820L router running firmware version 1.05B03 with remote management exposed to untrusted networks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataIf available, apply vendor firmware update. Otherwise, restrict network exposure, disable remote management interfaces, and monitor for indicators of compromise.
