CyberRota Analysis
AI-GeneratedThe vulnerability allows authenticated users with the "create product" permission in Roskus Prospero Flow CRM versions prior to 5.16.0 to upload malicious files disguised as images, leading to arbitrary JavaScript execution within the application. This occurs due to inadequate file validation, where files are only checked by their content and not their extensions, allowing HTML files to be executed as scripts. Organizations using affected versions of this CRM should prioritize patching to mitigate the risk of stored cross-site scripting (XSS) attacks.

Original NVD Description
Unrestricted Upload of File with Dangerous Type in the product photo upload in Roskus Prospero Flow CRM before 5.16.0 allows an authenticated user holding the create product permission (routine Seller role) to execute arbitrary JavaScript in the application origin. The photo validation rule classifies the file only by its content (magic bytes) and rejects only a fixed list of PHP extensions, while ProductSaveController::save() names the stored file using the client-supplied extension and copies it into the public web root. A file that begins with an image header and carries an HTML extension passes validation, is stored under public/asset/upload/product/, and is served with a text/html content type, turning the upload into first-party stored script execution.
