Descriptions

In OpenNMS Horizon, versions opennms-18.0.0-1 through opennms-27.1.0-1; OpenNMS Meridian, versions meridian-foundation-2015.1.0-1 through meridian-foundation-2019.1.18-1; meridian-foundation-2020.1.0-1 through meridian-foundation-2020.1.7-1 are vulnerable to Stored Cross-Site Scripting, since the function `createRequisitionedNode()` does not perform any validation checks on the input sent to the `node-label` parameter. Due to this flaw an attacker could inject an arbitrary script which will be stored in the database.

En OpenNMS Horizon, versiones opennms-18.0.0-1 hasta opennms-27.1.0-1; OpenNMS Meridian, versiones meridian-foundation-2015.1.0-1 hasta meridian-foundation-2019.1.18-1; versiones meridian-foundation-2020.1.0-1 hasta meridian-foundation-2020.1.7-1, son vulnerables a un ataque de tipo Cross-Site Scripting Almacenado, ya que la función "createRequisitionedNode()" no lleva a cabo ningún chequeo de comprobación en la entrada enviada hacia el parámetro "nodo -label". Debido a este fallo, un atacante podría inyectar un script arbitrario que será almacenado en la base de datos
