Descriptions

The "Log alert to a file" action within action management enables any Orion Platform user with Orion alert management rights to write to any file. An attacker with Orion alert management rights could use this vulnerability to perform an unrestricted file upload causing a remote code execution.

La acción "Log alert to a file" dentro de la administración de acciones permite a cualquier usuario de Orion Platform con derechos de administración de alertas de Orion escribir en cualquier archivo. Un atacante con derechos de administración de alertas de Orion podría usar esta vulnerabilidad para llevar a cabo una carga de archivos sin restricciones causando una ejecución de código remota

This vulnerability allows remote attackers to execute arbitrary code on affected installations of SolarWinds Orion Platform. Authentication is required to exploit this vulnerability.
The specific flaw exists within the handling of alert creation. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
