CVE-2018-17460
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 · uneditedInsufficient data validation in filesystem URIs in Google Chrome prior to 68.0.3440.75 allowed a remote attacker to spoof the contents of the Omnibox (URL bar) via a crafted domain name.
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 confidenceGoogle Chrome prior to 68.0.3440.75 had insufficient data validation in its filesystem URI handler, allowing a remote attacker to craft a malicious URI that would display spoofed content in the Omnibox (URL bar), misleading users about the actual domain they were visiting.

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.
-
Verify Google Chrome is installedOpen Chrome and navigate to chrome://version or go to Settings > About Chrome to view the browser versionAffected if Chrome browser is present on the endpoint
-
Determine installed Chrome versionLocate the "Chrome" section on the chrome://version page and record the version number displayed (format: XX.X.XXXX.XX)Affected if A version number is displayed
-
Compare version against affected rangeCompare your recorded version number to 68.0.3440.75 using standard version comparison (each numeric segment is compared left to right)Affected if The installed version is less than 68.0.3440.75 (for example, 68.0.3440.74 or any earlier version)
-
Confirm filesystem URI handling is accessibleThis vulnerability exploits the built-in filesystem: URI handler in Chrome; no additional configuration check is needed as this handler is available in all standard Chrome installationsAffected if Chrome is running with standard configuration and the filesystem URI scheme is supported
You are affected if the installed Google Chrome version is below 68.0.3440.75, as this version introduced sufficient data validation to prevent Omnibox URL spoofing via malicious filesystem URIs.

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 data68.0.3440.75
Upgrade Google Chrome to version 68.0.3440.75 or later. Organizations should deploy the browser update through their standard endpoint management systems and verify successful installation.
