CVE-2017-1000059
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 · uneditedLive Helper Chat version 2.06v and older is vulnerable to Cross-Site Scripting in the HTTP Header handling resulting in the execution of any user provided Javascript code in the session of other users.
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 · moderate confidenceLive Helper Chat versions 2.06v and older contains a stored Cross-Site Scripting (XSS) vulnerability in the HTTP Header handling component. User-supplied data within HTTP headers is rendered without proper sanitization or output encoding, allowing authenticated attackers to inject malicious JavaScript that executes in the browser sessions of other users who view the affected content.

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 installed Live Helper Chat versionLocate the version file or admin panel 'About' section to determine the running version of Live Helper ChatAffected if The installed version is 2.06 or any version lower than 2.06
-
Confirm HTTP Header handling feature is in useCheck if the system processes or displays HTTP header data, such as through admin panels, logs, or user profile information that renders header valuesAffected if The HTTP Header handling component is active and displays header values to users
-
Inspect stored header data for unsanitized contentReview any database tables or admin interfaces that store or display HTTP header information for unescaped HTML or script tagsAffected if Raw HTTP header values are rendered in the interface without HTML encoding
-
Check for existing malicious scripts in header-related fieldsSearch the database or configuration files for any stored script tags, javascript: URIs, or event handlers within fields that store header dataAffected if Malicious JavaScript code is found stored in header-related fields
You are affected if running Live Helper Chat version 2.06 or lower AND the HTTP Header handling component is enabled and displays header values without proper sanitization.

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 proper input validation and output encoding for all HTTP header values before they are displayed to users. Additionally, configure Content-Security-Policy headers to mitigate XSS execution.
