CVE-2015-2051
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 · uneditedThe D-Link DIR-645 Wired/Wireless Router Rev. Ax with firmware 1.04b12 and earlier allows remote attackers to execute arbitrary commands via a GetDeviceSettings action to the HNAP interface.
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-645 router firmware 1.04b12 and earlier contains a command injection vulnerability in its HNAP (Home Network Administration Protocol) interface. The GetDeviceSettings action fails to properly sanitize user input, allowing remote attackers to inject and execute arbitrary operating system commands on the device.

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 device modelAccess the router's web interface or check the device label to confirm it is a D-Link DIR-645 revision AxAffected if The device is not a D-Link DIR-645 (Rev. Ax)
-
Check the installed firmware versionLog into the router web interface and navigate to the Status or Administration section to view the firmware version, or use the router's built-in upgrade check featureAffected if The firmware version is 1.04b12 or earlier, or any version below 1.05b01
-
Verify HNAP interface accessibilityAttempt to access the HNAP endpoint on the router (typically http://routerIP/HNAP1 or check if the HNAP SOAP action responds)Affected if The HNAP interface is reachable from the network being tested
-
Determine if remote management is enabledCheck the router's Administration or Management settings for remote access/enable remote management options, and verify if the router's web interface is accessible from WAN IP addressesAffected if Remote management is enabled and the router is accessible from the internet or an untrusted network
A user is affected if they have a D-Link DIR-645 (Rev. Ax) router running firmware versions below 1.05b01 with the HNAP interface exposed to an untrusted network.
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.
dbcve · scoped1.05b01
Upgrade the D-Link DIR-645 firmware to a version newer than 1.04b12. If no patched firmware is available, disable remote HNAP access by restricting administrative interface access to trusted internal networks only.
Firmware version 1.05b01 or later
- Download the firmware version 1.05b01 or later from the official D-Link support site
- Access the router's web management interface via a web browser
- Navigate to the Administration or System settings section
- Locate the Firmware Upgrade option
- Upload the downloaded firmware file
- Wait for the upgrade process to complete (do not power off the router)
- After reboot, verify the firmware version in the router settings
