Descriptions

OpenNMS version 18.0.1 and prior are vulnerable to a stored XSS issue due to insufficient filtering of SNMP agent supplied data. By creating a malicious SNMP 'sysName' or 'sysContact' response, an attacker can store an XSS payload which will trigger when a user of the web UI views the data. This issue was fixed in version 18.0.2, released on September 20, 2016.

OpenNMS versiones 18.0.1 y anteriores, son vulnerables a un problema de tipo XSS almacenado debido a un filtrado insuficiente de los datos suministrados por el agente SNMP. Al crear una respuesta SNMP "sysName" o "sysContact" maliciosa, un atacante puede almacenar una carga útil de tipo XSS que será desencadenada cuando un usuario de la Interfaz web visualice los datos. Este problema se ha corregido en la versión 18.0.2, publicada el 20 de septiembre de 2016.
