CVE-2016-7509
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 · uneditedCross-site scripting (XSS) vulnerability in GLPI 0.90.4 allows remote authenticated attackers to inject arbitrary web script or HTML by attaching a crafted HTML file to a ticket.
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 confidenceCross-site scripting vulnerability in GLPI 0.90.4 allows authenticated users to inject malicious JavaScript/HTML by attaching crafted HTML files to tickets. When other users view or access the ticket attachment, the embedded script executes in their browser context.

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 GLPI versionLocate the GLPI version number in the application footer, administration panel, or version.php file in the GLPI root directoryAffected if version is exactly 0.90.4
-
Confirm ticket attachment feature is activeCheck if the ticket system and file attachment functionality are enabled in GLPI configuration under Setup > General > Setup or similar administration areaAffected if attachments are allowed on tickets
-
Verify HTML file upload is permittedCheck allowed file extensions in GLPI's document type configuration (typically under Setup > Dropdowns > Document Types) to see if .html or .htm extensions are permitted for uploadsAffected if .html or .htm file extensions are among allowed upload types for attachments
-
Identify if users can create ticketsConfirm that authenticated users have the ability to create tickets and attach files. Check user profile permissions for Ticket > Create and Document > CreateAffected if authenticated users can create tickets with file attachments
User is affected if running GLPI version 0.90.4 with the ticket attachment feature enabled and .html/.htm file uploads permitted for 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 dataUpgrade GLPI to a version where this vulnerability is patched, or implement server-side sanitization of HTML file attachments and content-type validation to block executable content from being uploaded.
