Descriptions

An issue was discovered in Backdrop CMS 1.14.x before 1.14.2. It doesn't sufficiently filter output when displaying file type descriptions created by administrators. An attacker could potentially craft a specialized description, then have an administrator execute scripting when viewing the list of file types, aka XSS. This vulnerability is mitigated by the fact that an attacker must have a role with the "Administer file types" permission.

Se detectó un problema en Backdrop CMS versiones 1.14.x anteriores a 1.14.2. No filtra suficientemente la salida cuando se despliegan descripciones de tipo de archivo creadas por parte de los administradores. Un atacante podría crear potencialmente una descripción especializada y luego hacer que un administrador ejecute secuencias de comandos cuando visualiza la lista de tipos de archivos, también se conoce como un XSS. Esta vulnerabilidad es mitigada por el hecho de que un atacante debe tener un rol con el permiso "Administer file types".
