CVE-2024-51023
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 · uneditedD-Link DIR_823G 1.0.2B05 was discovered to contain a command injection vulnerability via the Address parameter in the SetNetworkTomographySettings function. This vulnerability allows attackers to execute arbitrary OS commands via a crafted request.
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 confidenceD-Link DIR_823G firmware 1.0.2B05 contains a command injection vulnerability in the SetNetworkTomographySettings function where the Address parameter is not properly sanitized, allowing authenticated attackers to inject and execute arbitrary OS commands via crafted HTTP requests.

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 device modelAccess the device's web management interface or check the device label to confirm the model is D-Link DIR 823GAffected if Device model is not D-Link DIR 823G (different models are not affected)
-
Check firmware versionLog into the router's web interface and navigate to the Status or System Information page to view the firmware version, or check via SSH/Telnet if enabled using 'cat /proc/version' or 'nvram get firmversion'Affected if Firmware version is 1.0.2B05 exactly (this is the only affected version listed)
-
Verify web management interface accessibilityAttempt to access the router's HTTP/HTTPS web interface (typically at the default IP such as 192.168.0.1 or 192.168.1.1) from a browserAffected if The web interface is exposed to untrusted networks, allowing potential authenticated attackers to reach the vulnerable function
-
Check authentication statusDetermine if default administrator credentials are in use or if the management interface is accessible without authentication from the network segment you are evaluatingAffected if The administrative interface is accessible with valid credentials or weak/default credentials, enabling the attack vector for command injection
You are affected if you have a D-Link DIR 823G device running firmware version 1.0.2B05 with its web management interface accessible to untrusted networks or users.

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 dataApply vendor firmware patch if available; otherwise restrict administrative access to trusted networks/IPs or consider device replacement, as end-of-life devices may not receive security updates.
