Descriptions

The Shared Files WordPress plugin before 1.7.6 does not return the right Content-Type header for the specified uploaded file. Therefore, an attacker can upload an allowed file extension injected with malicious scripts.

El complemento Shared Files de WordPress anterior a 1.7.6 no devuelve el encabezado de tipo de contenido correcto para el archivo cargado especificado. Por lo tanto, un atacante puede cargar una extensión de archivo permitida inyectada con scripts maliciosos.

The Shared Files – Advanced File Sharing & Download Manager with Frontend Uploads plugin for WordPress is vulnerable to Stored Cross-Site Scripting via uploaded file content in all versions up to, and including, 1.7.5 due to the plugin not returning the correct 'Content-Type' header when viewing uploaded files. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in uploaded files that will execute whenever a user accesses the injected upload.
