Descriptions

In OpenNMS Horizon, versions opennms-17.0.0-1 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 `add()` performs improper validation checks on the input sent to the `foreign-source` parameter. Due to this flaw an attacker could bypass the existing regex validation and inject an arbitrary script which will be stored in the database.

En OpenNMS Horizon, versiones opennms-17.0.0-1 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 "add()" lleva a cabo chequeos de comprobación inapropiadas en la entrada enviada hacia el parámetro "foreign-source". Debido a este fallo, un atacante podría omitir la Comprobación de expresiones regulares existente e inyectar un script arbitrario que será almacenado en la base de datos
