Title
Joomla Extension - balbooa.com - Unauthenticated upload filename stored XSS in Balbooa Forms < 2.4.3.4
Summary
Joomla Extension - balbooa.com - Unauthenticated upload filename stored XSS in Balbooa Forms < 2.4.3.4 - The public form upload endpoint validates the uploaded file's extension and detected MIME type, but stores the attacker-supplied original multipart filename verbatim in `#__baforms_submissions_attachments.name`. A later anonymous form submission associates that temporary attachment with the newly created submission. When an administrator opens the submission, the component's JavaScript retrieves the stored attachment record and concatenates `file.name` directly into an HTML string. The complete string is assigned to `innerHTML`.
