CVE-2018-5411
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 · uneditedPixar's Tractor software, versions 2.2 and earlier, contain a stored cross-site scripting vulnerability in the field that allows a user to add a note to an existing node. The stored information is displayed when a user requests information about the node. An attacker could insert Javascript into this note field that is then saved and displayed to the end user. An attacker might include Javascript that could execute on an authenticated user's system that could lead to website redirects, session cookie hijacking, social engineering, etc. As this is stored with the information about the node, all other authenticated users with access to this data are also vulnerable.
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 confidenceStored cross-site scripting (XSS) vulnerability in Pixar's Tractor rendering management software versions 2.2 and earlier. An attacker can inject malicious JavaScript into a note field when adding a note to a node; this payload is persistently stored and executes in the browsers of all authenticated users who view that node's information.

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 if Pixar Tractor is installedLocate the Tractor installation directory or check for running processes related to Tractor (such as tractor-blade, tractor-engine, or tractor-dashboard). On Linux/Unix systems, common paths include /opt/pixar/tractor or ~/pixar/tractor. On Windows, check Program Files for a Pixar folder.Affected if Tractor software is present on the system
-
Determine the installed Tractor versionCheck the version by inspecting the Tractor engine or dashboard web interface (typically accessible on port 80/443), or look for a version file in the installation directory. Common version file locations include VERSION.txt, about.html, or the main executable's properties.Affected if The installed version is 2.2 or any version lower than 2.2
-
Verify the note field feature is accessibleConfirm that the Tractor web interface is accessible and that authenticated users have permission to view and add notes to nodes. The vulnerability exists in the note field when adding a note to a rendering node.Affected if The web interface is exposed and users can access node details with notes functionality
-
Check for existing malicious payloads in the databaseQuery the Tractor database (typically SQLite or similar) for any unusual JavaScript tags or event handlers in note fields. Look for patterns like <script>, javascript:, onload, onerror, or other XSS vectors stored in note records.Affected if Unexpected script tags or event handler attributes are found in note field records
You are affected if Pixar Tractor version 2.2 or earlier is installed and the web interface with note functionality is accessible to authenticated users.

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 dataImplement input validation and output encoding/sanitization on the note field to neutralize malicious scripts before storage and before rendering to users. Consider implementing Content Security Policy headers as defense-in-depth.
