CVE-2018-4941
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 · uneditedAdobe ColdFusion Update 5 and earlier versions, ColdFusion 11 Update 13 and earlier versions have an exploitable Cross-Site Scripting vulnerability. Successful exploitation could lead to information disclosure.
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 confidenceThis is a Cross-Site Scripting (XSS) vulnerability in Adobe ColdFusion versions Update 5 and earlier (for one release line) and Update 13 and earlier (for ColdFusion 11). The vulnerability allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to information disclosure such as session hijacking or theft of sensitive data.

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 ColdFusion edition and versionCheck the ColdFusion administrator console (typically at /CFIDE/administrator/) or look for version info in the installation directory's readme.txt or in the registry (Windows) or corresponding config files (Linux/Unix). The version string will show if you are running ColdFusion 11 or ColdFusion 2016.Affected if The installed version is ColdFusion 11.0 or ColdFusion 2016.
-
Determine ColdFusion 11 update levelIn ColdFusion 11, check the update level by viewing the administrator home page or the cfadmin version display. The update number is typically visible in the administrator footer or by inspecting the updates section.Affected if ColdFusion 11 is at Update 13 or earlier.
-
Determine ColdFusion 2016 update levelIn ColdFusion 2016, check the update level by viewing the administrator home page or the cfadmin version display. The update number is typically visible in the administrator footer or by inspecting the updates section.Affected if ColdFusion 2016 is at Update 5 or earlier.
-
Check for affected web endpointsReview your application's web endpoints that accept user input and return it without proper encoding. Focus on areas where user-supplied data is reflected in HTML output without sanitization.Affected if User input is reflected in responses without output encoding and the ColdFusion version/update is within the affected range.
You are affected if you run ColdFusion 11 with Update 13 or earlier, or ColdFusion 2016 with Update 5 or earlier, and have web endpoints that reflect user input without proper encoding.

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 dataApply the appropriate ColdFusion updates (Update 6 or later for the first line, Update 14 or later for ColdFusion 11) to patch the vulnerability. Additionally, implement output encoding and input validation on affected endpoints as a defense-in-depth measure.
