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
Xerox WorkCentre EC7836 before 073.050.059.25300 and EC7856 before 073.020.059.25300 devices allow XSS via Description pages.

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 · moderate confidence

Cross-site scripting (XSS) vulnerability in Xerox WorkCentre EC7836 (before 073.050.059.25300) and EC7856 (before 073.020.059.25300) multifunction devices allows injection of malicious scripts through the Description pages web interface.

MitigationUpdate firmware to version 073.050.059.25300 or later for EC7836, and 073.020.059.25300 or later for EC7856. Restrict web management interface access to authorized personnel and implement network segmentation to reduce exposure.

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. Identify the device model
    Access the device web interface or print a configuration page to confirm the model is Xerox WorkCentre EC7836 or EC7856.
    Affected if The device is not an EC7836 or EC7856 model.
  2. Locate the firmware version
    Log into the web management interface and navigate to the Device Information or Properties section, or print a configuration/report page from the device console.
    Affected if Unable to retrieve the firmware version information.
  3. Compare EC7836 firmware version
    If the device is EC7836, compare the installed firmware version number to 073.050.059.25300.
    Affected if The installed version is less than 073.050.059.25300.
  4. Compare EC7856 firmware version
    If the device is EC7856, compare the installed firmware version number to 073.020.059.25300.
    Affected if The installed version is less than 073.020.059.25300.
  5. Verify web interface exposure
    Confirm whether the Description pages web interface is accessible from network locations where untrusted users could inject scripts.
    Affected if The web management interface is exposed to untrusted users or networks.

The environment is affected if the device is a Xerox WorkCentre EC7836 running firmware below 073.050.059.25300, or an EC7856 running firmware below 073.020.059.25300, and the web interface is accessible.
