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
Xerox WorkCentre 3655, 3655i, 58XX, 58XXi, 59XX, 59XXi, 6655, 6655i, 72XX, 72XXi, 78XX, 78XXi, 7970, and 7970i devices before 073.xxx.086.15410 do not properly escape parameters in the support/remoteUI/configrui.php script, which can allow an unauthenticated attacker to execute OS commands 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

Multiple Xerox WorkCentre printer models contain an unauthenticated command injection vulnerability in the support/remoteUI/configrui.php script. The script fails to properly escape parameters before passing them to OS command execution, allowing remote attackers to inject and execute arbitrary operating system commands on affected devices.

MitigationUpgrade firmware to version 073.xxx.086.15410 or later. If immediate patching is not feasible, implement network segmentation and firewall rules to restrict access to the device's web management 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the WorkCentre model
    Access the device web interface or check the physical label to determine the exact model number (e.g., Workcentre 3655, 5865, 5875, 5890, or their i variants)
    Affected if The model is one of: 3655, 3655i, 5865, 5865i, 5875, 5875i, 5890, or 5890i
  2. Check the installed firmware version
    Log into the web管理界面，导航到设备信息或系统设置页面，查看固件版本信息。或者通过SNMP或设备菜单获取版本号。
    Affected if The firmware version is below 073.060.086.15410 for 3655/3655i models, or below 073.190.086.15410 for 5865/5865i/5875/5875i/5890/5890i models
  3. Verify the vulnerable script is accessible
    Attempt to access the URI /support/remoteUI/configrui.php on the device web server using a GET request
    Affected if The script returns an HTTP 200 response, indicating it exists and is accessible
  4. Confirm web management interface is enabled
    Verify the device web server is running and reachable on the network by accessing the main page or remoteUI portal
    Affected if The web interface is exposed and responds to requests, enabling the attack surface for this vulnerability

The device is affected if it is a WorkCentre model from the affected list AND its firmware version is below the fixed thresholds AND the web management interface with the vulnerable script is accessible.

Interim mitigation

Upgrade firmware to version 073.xxx.086.15410 or later. If immediate patching is not feasible, implement network segmentation and firewall rules to restrict access to the device's web management interface.

Recommended fix High confidence

Xerox WorkCentre firmware 073.060.086.15410 or later (3655/3655i) / 073.190.086.15410 or later (58XX, 58XXi, 59XX, 59XXi)

  1. Obtain the firmware update from Xerox support (securitydocs.business.xerox.com) or your authorized Xerox reseller
  2. Access the WorkCentre device web interface or admin console
  3. Navigate to the firmware update section
  4. Upload and install firmware version 073.060.086.15410 or later for WorkCentre 3655/3655i models
  5. Upload and install firmware version 073.190.086.15410 or later for WorkCentre 58XX, 58XXi, 59XX, 59XXi models
  6. After reboot, verify the firmware version matches the fixed release in the device information panel
  7. Confirm the vulnerability is remediated by testing that the support/remoteUI/configrui.php endpoint no longer accepts arbitrary command injection
Caveat Firmware upgrades may temporarily interrupt device availability; ensure backup of configuration before proceeding
