CVE-2018-20769
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 · uneditedAn issue was discovered on Xerox WorkCentre 3655, 3655i, 58XX, 58XXi, 59XX, 59XXi, 6655, 6655i, 72XX, 72XXi, 78XX, 78XXi, 7970, 7970i, EC7836, and EC7856 devices before R18-05 073.xxx.0487.15000. There is a Local File Inclusion vulnerability.
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 confidenceThis is a Local File Inclusion (LFI) vulnerability affecting multiple Xerox WorkCentre printer models. The vulnerability allows unauthenticated attackers to access local files on the device's filesystem by manipulating file path parameters in web requests. This can expose sensitive system files, configuration data, and credentials stored on the device.

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 Xerox WorkCentre modelLocate the model number on the device physical label or check the web interface login page for the model nameAffected if The model is one of: 3655i, 3655, 5890i, 5865i, 5875i, 5845, 5865, or 5875
-
Determine the installed firmware versionAccess the device web interface and navigate to the Properties or About page to view the firmware version, or use the embedded web server status pageAffected if The firmware version is below 073.060.048.15000 for 3655i/3655 models, or below 073.190.048.15000 for all other affected models
-
Verify web management interface accessibilityConfirm the device HTTP/HTTPS web interface is reachable on the network by attempting to access the device IP address from a browserAffected if The web interface is exposed and reachable on the network (this is required for the LFI attack vector)
-
Check for suspicious file access patterns in logsReview device system logs or web server access logs for unusual requests containing directory traversal patterns such as '../' or absolute file paths like '/etc/passwd'Affected if Logs show requests with file path parameters that may indicate exploitation attempts
A user is affected if they have a matching model with firmware below the specified version AND the device web management interface is network-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 data073.060.048.15000073.190.048.15000
Apply firmware version R18-05 073.xxx.0487.15000 or later to affected Xerox WorkCentre devices. If patching is not immediately possible, restrict network access to the device's web management interface using firewall rules or VLAN segmentation.
