Descriptions

In OpenNMS Horizon, versions opennms-1-0-stable 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-2020.1.6-1 are vulnerable to Stored Cross-Site Scripting, since the function `validateFormInput()` performs improper validation checks on the input sent to the `groupName` and `groupComment` parameters. Due to this flaw, an authenticated attacker could inject arbitrary script and trick other admin users into downloading malicious files which can cause severe damage to the organization using opennms.

En OpenNMS Horizon, versiones opennms-1-0-stable 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-2020.1.6-1, son vulnerables a ataques de tipo Cross-Site Scripting almacenados, ya que la función "validateFormInput()" lleva a cabo validaciones de comprobación inapropiadas en la entrada enviada a los parámetros "groupName" y "groupComment". Debido a este fallo, un atacante autenticado podría inyectar un script arbitrario y engañar a otros usuarios administradores para que descarguen archivos maliciosos que pueden causar daños severos a la organización usando opennms
