Descriptions

Persistent XSS in /course/modedit.php of Moodle through 3.7.2 allows authenticated users (Teacher and above) to inject JavaScript into the session of another user (e.g., enrolled student or site administrator) via the introeditor[text] parameter. NOTE: the discoverer and vendor disagree on whether Moodle customers have a reasonable expectation that anyone authenticated as a Teacher can be trusted with the ability to add arbitrary JavaScript (this ability is not documented on Moodle's Teacher_role page). Because the vendor has this expectation, they have stated "this report has been closed as a false positive, and not a bug."

** EN DISPUTA ** Un vulnerabilidad de tipo XSS persistente en el archivo /course/modedit.php de Moodle versiones hasta 3.7.2, permite a usuarios autenticados (Teacher y superior) inyectar JavaScript en la sesión de otro usuario (por ejemplo, enrolled student o site administrator) por medio del parámetro introeditor[text]. NOTA: el descubridor y el suplidor no están de acuerdo sobre si los clientes de Moodle tienen una expectativa razonable de que cualquier persona autenticada como Teacher pueda ser confiable en la capacidad de agregar JavaScript arbitrario (esta capacidad no está documentada en la página Teacher_role de Moodle). Debido a que el suplidor tiene esta expectativa, ha declarado que "este informe se ha cerrado como un falso positivo y no como un error".
