The Balbooa Forms extension for Joomla versions prior to 2.4.3.4 is vulnerable to an unauthenticated stored cross-site scripting (XSS) attack due to improper handling of uploaded file names. Attackers can exploit this vulnerability to inject malicious scripts that execute in the context of an administrator's session when they view submissions. Joomla site administrators using affected versions should prioritize patching this vulnerability to mitigate potential exploitation.

Original NVD Description

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`.
