CVE-2017-6067
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 · uneditedSymphony 2.6.9 has XSS in publish/notes/edit/##/saved/ via the bottom form field.
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 confidenceSymphony CMS 2.6.9 contains a stored Cross-Site Scripting (XSS) vulnerability in the notes editor at publish/notes/edit/##/saved/. The 'bottom form field' does not properly sanitize user input, allowing injection of malicious JavaScript that executes when other users view the notes.

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 Symphony CMS versionLocate the version file or admin panel that displays the Symphony CMS version number. Common locations include a version.php file in the core directory or the system overview in the admin backend.Affected if The installed version is exactly 2.6.9 (no other versions are listed as affected).
-
Confirm notes feature is accessibleNavigate to the notes editor interface at publish/notes/edit/ in the Symphony admin panel, or check if the notes module is enabled in the system configuration.Affected if The notes functionality exists and is accessible to users.
-
Examine the notes form field configurationInspect the HTML source of the notes editor page (publish/notes/edit/##/saved/) and locate the 'bottom form field' element. Determine whether output encoding or input validation is being applied to this field.Affected if The bottom form field accepts user input without sanitization and reflects it back without proper encoding.
A user is affected only if Symphony CMS version 2.6.9 is installed AND the notes editor feature is accessible AND the bottom form field lacks input sanitization or output 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 proper input validation and output encoding to the notes form field. Upgrade to a patched version of Symphony CMS if available, or implement contextual output escaping for all user-supplied data in form fields.
