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
Some Xerox printers (such as the Phaser 3320 V53.006.16.000) were affected by a buffer overflow vulnerability in the Content-Type HTTP Header of the web application that would allow an attacker to execute arbitrary code on the device.

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 buffer overflow vulnerability exists in the web application of affected Xerox printers (such as Phaser 3320 V53.006.16.000) in the handling of the Content-Type HTTP header. By sending a specially crafted HTTP request with an oversized Content-Type value, an attacker can overflow a buffer and achieve arbitrary code execution on the device.

MitigationApply the vendor-supplied firmware update from Xerox to patched versions. Until patched, restrict network access to the printer's web interface using network segmentation or firewall rules to minimize 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 printer model
    Access the printer's web interface or print a configuration page to confirm the device is a Xerox Phaser 3320. The model number is typically displayed on the home page of the embedded web server or on the printed test page under 'Device Information' or 'Printer Status'.
    Affected if The device is not a Xerox Phaser 3320 - this vulnerability only affects that specific model.
  2. Check the installed firmware version
    In the printer's web interface, navigate to the Home or Status page and locate the Firmware version field. Alternatively, print a configuration page from the printer control panel and look for the firmware revision listed in the device information section.
    Affected if The firmware version is exactly v53.006.16.000 - this is the only version listed as affected in the CVE.
  3. Verify the web application is enabled
    Confirm that the embedded web server (HTTP/HTTPS interface) is turned on. This is typically found in the printer's network settings or under 'Services' > 'Web Server' in the web interface. If you can access the login page of the printer's web UI, the web application is enabled.
    Affected if The web application is disabled - the vulnerability exists in the web application handling of the Content-Type header, so if the web interface is completely turned off, the attack surface does not exist.

You are affected only if you have a Xerox Phaser 3320 device running firmware version v53.006.16.000 with the embedded web server enabled.

Mitigation

Apply the vendor-supplied firmware update from Xerox to patched versions. Until patched, restrict network access to the printer's web interface using network segmentation or firewall rules to minimize exposure.
