CVE-2018-20767
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 authenticated remote command execution.
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 an authenticated remote command execution vulnerability in Xerox WorkCentre multifunction printer devices. An attacker with valid device credentials can execute arbitrary commands on the affected device, leading to full device compromise. The vulnerability affects 16 different WorkCentre models before firmware version R18-05 073.xxx.0487.15000.

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 WorkCentre modelAccess the device web interface or check the physical label to confirm the exact model number (e.g., Workcentre 3655i, 5865, 5875i, etc.)Affected if The model matches one of the affected variants listed in the CVE (3655i, 3655, 5890i, 5865i, 5875i, 5845, 5865, 5875)
-
Check the installed firmware versionLog into the device web interface and navigate to the Properties or Device Information section to view the firmware version, or use the front panel display if availableAffected if The firmware version is below 073.060.048.15000 (for 3655/3655i models) or below 073.190.048.15000 (for 5890i, 5865i, 5875i, 5845, 5865, 5875 models)
-
Verify remote management interface is enabledCheck the device network settings via the web interface to confirm that HTTP/HTTPS management access is enabled, or attempt to access the device login page from a network clientAffected if The web-based management interface is accessible over the network
-
Confirm authentication is configuredCheck the Security or Authentication settings in the device web interface to verify that device credentials are set (even weak or default credentials satisfy the authentication requirement for this CVE)Affected if Local device authentication is enabled or configured, even if using default credentials
The device is affected if it is a Xerox WorkCentre from the listed models AND its firmware version is below the specified thresholds AND the management interface with authentication 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 data073.060.048.15000073.190.048.15000
Apply the vendor-supplied firmware update R18-05 073.xxx.0487.15000 or later to all affected devices. Until patched, restrict network access to device management interfaces and enforce strong authentication credentials.
