CVE-2002-1836
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 · uneditedThe default configuration of Xerox DocuTech 6110 and DocuTech 6115 exports certain NFS shares to the world with world writable permissions, which may allow remote attackers to modify sensitive files.
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 confidenceThe Xerox DocuTech 6110 and 6115 production printers ship with a default NFS configuration that exports certain shares to the entire internet (0.0.0.0/0) with world-writable permissions. This allows any remote attacker to mount these shares and modify sensitive documents or system files 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 device modelCheck the device model number through its web interface, front panel display, or system information page. Confirm it is a Xerox DocuTech 6110 or Xerox DocuTech 6115.Affected if The device is a Xerox DocuTech 6110 or 6115 model.
-
Verify if NFS service is enabledAccess the device administration interface or system services list and check whether the NFS (Network File System) service is currently running or enabled.Affected if NFS service is enabled and running on the device.
-
Locate the NFS exports configurationOn the device filesystem, locate the NFS export configuration file (commonly /etc/exports or equivalent). This file defines what directories are shared via NFS.Affected if An NFS export configuration file exists on the device.
-
Inspect NFS export entries for permissive accessRead the NFS exports configuration file and examine each export entry. Look for entries that specify 0.0.0.0/0, an asterisk (*), or any other wildcard that grants access to the entire internet.Affected if Any share is exported to 0.0.0.0/0 or an equivalent wildcard allowing unrestricted network access.
-
Check shared directory permissionsExamine the filesystem permissions (using ls -ld or equivalent) on the directories listed in the NFS exports configuration. Verify whether they are set to world-writable (mode 777 or similar).Affected if The exported directories have world-writable permissions allowing any user to modify content.
The device is affected if it is a Xerox DocuTech 6110 or 6115 with NFS enabled, and the NFS exports are configured to allow access from 0.0.0.0/0 with world-writable directory permissions.
Generated from the published advisory. Verify against your own configuration.
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 dataRestrict NFS exports to specific authorized IP addresses or subnets, and remove world-writable permissions from shared directories. If NFS is not required, disable the NFS service entirely.
