Durante las construcciones CI/CD, es posible guardar los artefactos de construcci\u00f3n para su posterior recuperaci\u00f3n. Puede accederse a ellos mediante la interfaz web de OneDev despu\u00e9s de una ejecuci\u00f3n con \u00e9xito de una construcci\u00f3n. Estos archivos de artefactos son servidos por el servidor web en el mismo contexto que la Interfaz de Usuario sin m\u00e1s restricciones. Esto conlleva a un ataque de tipo Cross-Site Scripting (XSS) cuando un usuario crea un artefacto de construcci\u00f3n que contiene HTML. Cuando es accedido al artefacto, el contenido es renderizado por el navegador, incluyendo cualquier JavaScript que contenga. Como todas las cookies (excepto la de RememberMe) no establecen el flag HttpOnly, un atacante podr\u00eda robar la sesi\u00f3n de una v\u00edctima y usarla para suplantar su identidad. Para explotar este problema, los atacantes deben ser capaces de modificar el contenido de los artefactos, lo que normalmente significa que deben ser capaces de modificar las especificaciones de construcci\u00f3n de un proyecto. La explotaci\u00f3n requiere que la v\u00edctima haga clic en un enlace del atacante. Puede usarse para elevar los privilegios al dirigirse a administradores de una instancia de OneDev. En el peor de los casos, esto puede conllevar a una ejecuci\u00f3n de c\u00f3digo arbitrario en el servidor, ya que los administradores pueden crear ejecutores de shell de servidor y usarlos para ejecutar cualquier comando en el servidor.
