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 Authentication Cookie 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 · moderate confidence

A buffer overflow vulnerability in the Authentication Cookie handling mechanism of the Xerox Phaser 3320 printer web interface allows remote attackers to overflow the cookie buffer and execute arbitrary code on the device.

MitigationApply vendor-supplied firmware updates to patch the vulnerability. If patches are unavailable, restrict network access to the printer management interface and implement network segmentation to limit 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. Confirm device model is Xerox Phaser 3320
    Access the printer web interface (usually http://<printer-ip>) or print a configuration page from the printer control panel to verify the model number displays as Phaser 3320
    Affected if The device is not a Xerox Phaser 3320 printer
  2. Check installed firmware version
    In the web interface, navigate to the Status or Properties page to view the firmware version, or print a configuration/status page from the printer control panel
    Affected if The firmware version displayed equals v53.006.16.000 exactly
  3. Verify web management interface is enabled
    Attempt to access the printer web interface at http://<printer-ip> or https://<printer-ip> - if the login page loads, the web interface is active
    Affected if The web interface is accessible and the device runs firmware version v53.006.16.000

You are affected if the device is a Xerox Phaser 3320 with firmware version exactly v53.006.16.000 and the web management interface is accessible.
