CVE-2019-17353
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue discovered on D-Link DIR-615 devices with firmware version 20.05 and 20.07. wan.htm can be accessed directly without authentication, which can lead to disclosure of information about the WAN, and can also be leveraged by an attacker to modify the data fields of the page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe D-Link DIR-615 router with firmware versions 20.05 and 20.07 contains an authentication bypass vulnerability in the wan.htm page. This page, which displays WAN (Wide Area Network) configuration settings, can be accessed directly by unauthenticated attackers via the web interface, allowing both disclosure of sensitive WAN configuration information and modification of the data fields on that page.

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.
-
Identify the router modelAccess the router's web interface and check the device information page, or look for the model number on the physical device labelAffected if The device is not a D-Link DIR-615, then it is not affected by this specific CVE
-
Check the firmware versionLog into the router's web interface and navigate to the Status or System section to view the firmware version, or check the release notes/backup configuration fileAffected if The firmware version is either 20.05 or 20.07, making it vulnerable to this authentication bypass
-
Test unauthenticated access to wan.htmOpen a web browser and navigate to http://[router-ip]/wan.htm without logging in or providing any credentialsAffected if The page loads and displays WAN configuration settings without requiring authentication, confirming the vulnerability is present
-
Inspect WAN configuration for unauthorized changesCompare the current WAN settings (IP address, subnet, gateway, DNS servers, VLAN ID if applicable) against known-good baseline values or contact your ISP to verify settingsAffected if WAN settings have been changed from expected values or show configuration inconsistencies indicating unauthorized modification
A D-Link DIR-615 router running firmware version 20.05 or 20.07 that allows unauthenticated access to the wan.htm page is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
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 an updated firmware version is available from D-Link, apply it immediately. If no patch is available, restrict external access to the router's web management interface using firewall rules or disable remote administration entirely.
