CVE-2021-38484
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 · uneditedInHand Networks IR615 Router's Versions 2.3.0.r4724 and 2.3.0.r4870 do not have a filter or signature check to detect or prevent an upload of malicious files to the server, which may allow an attacker, acting as an administrator, to upload malicious files. This could result in cross-site scripting, deletion of system files, and remote code execution.
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 InHand Networks IR615 Router versions 2.3.0.r4724 and 2.3.0.r4870 contain a file upload vulnerability in the web interface. The firmware lacks proper file validation mechanisms (no filter or signature check) when processing uploaded files, allowing an authenticated administrator to upload arbitrary files including malicious executables. This can lead to cross-site scripting attacks, deletion of system files, and potentially remote code execution.

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 web interface or CLI and confirm the device model is InHand Networks IR615. Check the device label, web UI header, or system information page.Affected if The device is not an IR615 model, then this specific CVE does not apply.
-
Determine the installed firmware versionLocate the firmware version in the router web interface (typically under System > Firmware, Status, or About page) or via CLI command such as 'version' or 'show system info'. Compare the version number to the affected versions: 2.3.0.r4724 and 2.3.0.r4870.Affected if The firmware version matches exactly 2.3.0.r4724 or 2.3.0.r4870, then the device is running a vulnerable version.
-
Verify the web interface is accessibleAttempt to reach the router web interface via HTTP/HTTPS on the configured management IP address. Confirm the login page loads.Affected if The web interface is exposed to untrusted networks (such as the internet), then the attack surface for this vulnerability exists.
-
Check for administrative accessVerify if administrative credentials are configured for the router. This can be confirmed by attempting to log in or by reviewing access control settings.Affected if An authenticated administrator account exists and is accessible, which is required for the file upload vulnerability to be exploitable.
-
Locate file upload functionalityIn the router web interface, navigate to sections that may accept file uploads such as firmware upgrade, configuration import, certificate upload, or file management sections.Affected if File upload functionality is present and does not enforce file type validation or signature checking, the vulnerability is present.
The environment is affected if the device is an IR615 router running firmware version 2.3.0.r4724 or 2.3.0.r4870, the web interface is accessible, and an authenticated administrator can access file upload features.
