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 · unedited
Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Microchip TimeProvider 4100 (data plot modules) allows Reflected XSS.This issue affects TimeProvider 4100: from 1.0 before 2.4.7.

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 confidence

A reflected XSS vulnerability exists in the data plot modules of Microchip TimeProvider 4100. The web interface fails to properly sanitize user-supplied input, allowing attackers to inject malicious scripts that execute in the context of legitimate users' sessions when the crafted input is reflected back in a web page response.

MitigationUpdate Microchip TimeProvider 4100 firmware to version 2.4.7 or later to obtain the patched code that properly neutralizes input during web page generation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check firmware version
    Access the device through its CLI or web interface and retrieve the installed firmware version. This is typically found in the system status or About section of the web UI, or via 'show version' command in the CLI.
    Affected if Version is 1.0 or higher but below 2.4.7 (the affected range)
  2. Confirm web interface is enabled
    Verify that the TimeProvider 4100 web interface (HTTP/HTTPS) is enabled and accessible. Check the device network configuration to confirm the web service is running.
    Affected if Web interface is enabled and exposed on the network
  3. Identify data plot module accessibility
    Locate the data plot functionality within the web interface. Navigate to the data plot modules where user-supplied input is reflected in the response, such as in graph plotting or data visualization pages.
    Affected if Data plot modules are accessible and accept user input that gets reflected in the page response
  4. Inspect HTTP response for input reflection
    Submit a test payload containing harmless characters (such as <test>) in the data plot input fields and examine the HTTP response to see if the input is reflected back without proper encoding.
    Affected if User input is returned in the response without sanitization or encoding

The device is affected if the firmware version falls within 1.0 to 2.4.6 and the web interface with data plot modules is accessible.

Upgrade available Upgrade to 2.4.7 or later
Fixed in 2.4.7
Interim mitigation

Update Microchip TimeProvider 4100 firmware to version 2.4.7 or later to obtain the patched code that properly neutralizes input during web page generation.

Recommended fix High confidence

TimeProvider 4100 Firmware version 2.4.7

  1. 1. Backup the current TimeProvider 4100 configuration before initiating any firmware update.
  2. 2. Download the TimeProvider 4100 Firmware version 2.4.7 from the official Microchip support portal or vendor website.
  3. 3. Access the TimeProvider 4100 web management interface using an administrative account.
  4. 4. Navigate to the firmware upgrade section (typically under Administration or System Settings).
  5. 5. Upload the firmware file version 2.4.7 and initiate the upgrade process.
  6. 6. Wait for the upgrade to complete - do not power off the device during this process.
  7. 7. After reboot, verify the firmware version is displayed as 2.4.7 in the system information page.
  8. 8. Test that the data plot modules function correctly and the XSS vulnerability is no longer present.
