Descriptions

An issue was discovered in the FileImporter extension for MediaWiki before 1.34.4. An attacker can import a file even when the target page is protected against "page creation" and the attacker should not be able to create it. This occurs because of a mishandled distinction between an upload restriction and a create restriction. An attacker cannot leverage this to overwrite anything, but can leverage this to force a wiki to have a page with a disallowed title.

Se detectó un problema en la extensión FileImporter para MediaWiki versiones anteriores a 1.34.4.&#xa0;Un atacante puede importar un archivo incluso cuando la página de destino está protegida contra "page creation" y el atacante no debería poder crearlo.&#xa0;Esto ocurre debido a una distinción manejada inapropiadamente entre una restricción de carga y una restricción de creación.&#xa0;Un atacante no puede aprovechar esto para sobrescribir cualquier cosa, pero puede aprovechar esto para obligar a un wiki a tener una página con un título no permitido
