Descriptions

An issue was discovered in Backdrop CMS 1.13.x before 1.13.5 and 1.14.x before 1.14.2. It doesn't sufficiently filter output when displaying certain block descriptions created by administrators. An attacker could potentially craft a specialized description, then have an administrator execute scripting when configuring a layout, aka XSS. This issue is mitigated by the fact that the attacker would be required to have the permission to create custom blocks, which is typically an administrative task.

Se detectó un problema en Backdrop CMS versiones 1.13.x anteriores a 1.13.5 y versiones 1.14.x anteriores a 1.14.2. No filtra suficientemente la salida cuando se despliegan ciertas descripciones de bloque creadas por parte de los administradores. Un atacante podría crear potencialmente una descripción especializada y luego hacer que un administrador ejecute secuencias de comandos al configurar un diseño, también se conoce como un XSS. Este problema es mitigado por el hecho de que el atacante debería tener permiso para crear bloques personalizados, que generalmente es una tarea administrativa.
