CVE-2022-26974
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 · uneditedBarco Control Room Management Suite web application, which is part of TransForm N before 3.14, is exposing a file upload mechanism. Lack of input sanitization in the upload mechanism leads to reflected XSS.
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 confidenceThe Barco TransForm N web application before version 3.14 exposes a file upload mechanism that lacks proper input sanitization. This allows attackers to inject malicious script through uploaded filenames or metadata that gets reflected in server responses without encoding, leading to reflected XSS against users who view upload confirmation pages or file listings.

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 the TransForm N versionAccess the web application admin interface or check the software inventory/system information to locate the installed version number of Barco TransForm NAffected if The installed version is below 3.14.1 (any version 3.x before 3.14.1, or earlier major versions)
-
Locate the file upload endpointExamine the web application's available modules and navigation to confirm whether a file upload feature exists; typically found in admin panels, configuration pages, or document management sectionsAffected if The file upload functionality is present and accessible to users (regardless of privilege level)
-
Test filename reflection in responsesUpload a test file with a filename containing HTML/script characters (such as <script>test</script>.txt) and observe whether these characters appear unencoded in the subsequent HTTP response or file listing pageAffected if The uploaded filename is reflected in the response without HTML encoding (characters appear as raw HTML/script rather than escaped entities)
You are affected if your TransForm N version is below 3.14.1 AND the file upload feature is enabled and accessible in your environment.

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.
dbcve · scoped3.14.1
Upgrade TransForm N to version 3.14 or later. Additionally, implement strict input validation and output encoding for all file upload parameters (filenames, content types) before reflecting them in any HTTP response.
3.14.1 or later
- Upgrade Barco Control Room Management Suite (TransForm N) to version 3.14.1 or later to remediate the reflected XSS vulnerability in the file upload mechanism
