Descriptions

An issue was discovered in OpenNMS Horizon before 26.0.1, and Meridian before 2018.1.19 and 2019 before 2019.1.7. The ActiveMQ channel configuration allowed for arbitrary deserialization of Java objects (aka ActiveMQ Minion payload deserialization), leading to remote code execution for any authenticated channel user regardless of its assigned permissions.

Se detectó un problema en OpenNMS Horizon versiones anteriores a 26.0.1 y Meridian versiones anteriores a 2018.1.19 y versiones 2019 anteriores a 2019.1.7. La configuración del canal ActiveMQ permitió la deserialización arbitraria de objetos Java (también se conoce cmo deserialización de la carga útil de ActiveMQ Minion), conllevando a una ejecución de código remota para cualquier usuario del canal autenticado, sin importar sus permisos asignados.
