Descriptions

The affected product is vulnerable to the handling of serialized data. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data on the Ignition 8 Gateway (versions prior to 8.0.10) and Ignition 7 Gateway (versions prior to 7.9.14), allowing an attacker to obtain sensitive information.

El producto afectado es vulnerable al manejo de datos serializados. El problema resulta de la falta de una comprobación apropiada de los datos suministrados por el usuario, lo que puede resultar en una deserialización de datos no confiables en Ignition 8 Gateway (versiones anteriores a 8.0.10) y Ignition 7 Gateway (versiones anteriores a la 7.9.14), permitiendo a un atacante obtener información confidencial

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Inductive Automation Ignition. Authentication is not required to exploit this vulnerability.
The specific flaw exists with the handling of serialized data. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
