CVE-2020-26162
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 · uneditedXerox 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 confidenceCross-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.

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 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.
-
Locate the firmware versionLog 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.
-
Compare EC7836 firmware versionIf 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.
-
Compare EC7856 firmware versionIf 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.
-
Verify web interface exposureConfirm 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.

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 data073.020.059.25300073.050.059.25300
Update 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.
