CVE-2023-24762
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 · uneditedOS Command injection vulnerability in D-Link DIR-867 DIR_867_FW1.30B07 allows attackers to execute arbitrary commands via a crafted LocalIPAddress parameter for the SetVirtualServerSettings to HNAP1.
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 confidenceOS command injection vulnerability in D-Link DIR-867 router firmware (DIR_867_FW1.30B07). The HNAP1 SetVirtualServerSettings function fails to sanitize the LocalIPAddress parameter, allowing unauthenticated 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 modelCheck the label on the router or log into the web management interface to confirm the device is a D-Link DIR-867Affected if The device is not a D-Link DIR-867 router - this specific vulnerability applies only to this model
-
Check the installed firmware versionLog into the router web interface and navigate to the Status or Management section to view the firmware version, or use the command line and check via telnet/SSH if availableAffected if The firmware version is 1.30B07 exactly - this is the only affected version listed for this CVE
-
Verify HNAP1 service availabilityAttempt to access the HNAP1 SOAP endpoint on the router (typically at /HNAP1/ or check if port 80/443 responds to HNAP1 requests)Affected if The HNAP1 service is exposed and accessible on the device - this is the vulnerable service where the injection occurs
-
Confirm Virtual Server feature is presentCheck if the router web interface includes a Virtual Server or Port Forwarding settings section under the NAT or Firewall settingsAffected if The Virtual Server settings interface is present and accessible - the vulnerable SetVirtualServerSettings function handles this feature
-
Assess network exposure of management interfaceDetermine if the router HTTP/HTTPS management ports are reachable from untrusted network segments or the internetAffected if The router management interface is accessible from outside the trusted local network - this is a pre-authentication flaw exploitable without credentials
You are affected if you have a D-Link DIR-867 router running firmware version 1.30B07 with the HNAP1 service exposed on your network.

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 dataThis is a critical pre-authentication vulnerability in an end-of-life consumer router with no vendor patch available. Primary mitigations include network isolation, replacing the device with a supported model, or implementing strict firewall rules to block external access to the router's management interface.
