CVE-2023-4523
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 · uneditedReal Time Automation 460 Series products with versions prior to v8.9.8 are vulnerable to cross-site scripting, which could allow an attacker to run any JavaScript reference from the URL string. If this were to occur, the gateway's HTTP interface would redirect to the main page, which is index.htm.
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 RTA 460 Series gateway web interface contains a reflected cross-site scripting vulnerability in versions prior to v8.9.8. User-supplied JavaScript can be injected via the URL string and executed in the context of the user's browser, leading to potential session hijacking or credential theft. The vulnerable endpoint reflects the unsanitized input back to the user.

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 device's web interface or check the device label/metadata to confirm it is an RTA 460 Series gateway. The device typically displays its model name on the login page or in the system information section.Affected if The device is not an RTA 460 Series gateway - this CVE does not apply to other models.
-
Determine the installed firmware versionLog into the web interface and navigate to System > Status, System > About, or a similar information page. The firmware version is typically displayed as a version number (e.g., v8.9.7, v8.9.6). Alternatively, check the boot log or system diagnostics if CLI access is available.Affected if The firmware version is displayed as lower than v8.9.8 (for example, v8.9.7, v8.9.5, or earlier). Versions prior to 8.9.8 are affected.
-
Verify the web interface is enabledConfirm that the HTTP or HTTPS web management interface is active by attempting to access the device's IP address in a browser. The login page should load.Affected if The web interface is accessible and running. The reflected XSS only executes when a user interacts with the vulnerable endpoint via the browser.
-
Check for the vulnerable URL reflection behaviorInspect URLs used in the web interface, particularly any parameters that might reflect back in the response (such as in error messages, navigation state, or search fields). Look for unsanitized reflection of input in the HTML source.Affected if The web interface reflects URL parameters or path segments back into the rendered page without proper sanitization. This confirms the XSS vulnerability is present and exploitable.
You are affected if the device is an RTA 460 Series gateway running firmware version lower than v8.9.8 and the web interface is accessible, as the reflected XSS vulnerability exists in versions prior to the fix.

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 · scoped8.9.8
Upgrade the RTA 460 Series firmware to version v8.9.8 or later to obtain the vendor fix. If immediate patching is not possible, restrict network access to the device's HTTP management interface and monitor for suspicious URL patterns.
460 Series Firmware v8.9.8 or later
- Identify the current firmware version of the Real Time Automation 460 Series device
- Download firmware version 8.9.8 or later from the official Real Time Automation vendor
- Access the device's web interface or console to initiate the firmware upgrade process
- Upload and apply the new firmware version following the vendor's documented upgrade procedure
- After upgrade, verify the device is running firmware version 8.9.8 or later
- Confirm the XSS vulnerability is remediated by testing that JavaScript in URL parameters is no longer executed
