CVE-2022-43996

The csaf_provider package before 0.8.2 allows XSS via a crafted CSAF document uploaded as text/html. The endpoint upload allows valid CSAF advisories (JSON format) to be uploaded with Content-Type text/html and filenames ending in .html. When subsequently accessed via web browser, these advisories are served and interpreted as HTML pages. Such uploaded advisories can contain JavaScript code that will execute within the browser context of users inspecting the advisory.

Summary		(es) El paquete csaf_provider anterior a 0.8.2 permite XSS a través de un documento CSAF diseñado y cargado como texto/html. La carga del endpoint permite cargar avisos CSAF válidos (formato JSON) con texto/html de tipo de contenido y nombres de archivos que terminan en .html. Cuando se accede posteriormente a través de un navegador web, estos avisos se entregan e interpretan como páginas HTML. Dichos avisos cargados pueden contener código JavaScript que se ejecutará dentro del contexto del navegador de los usuarios que inspeccionan el aviso.
