Descriptions

A CWE-502: Deserialization of untrusted data vulnerability exists that could allow an attacker
logged in with a user level account to gain higher privileges by providing a harmful serialized
object.

Existe una vulnerabilidad CWE-502: deserialización de datos no confiables que podría permitir que un atacante que haya iniciado sesión con una cuenta de nivel de usuario obtenga mayores privilegios al proporcionar un objeto serializado dañino.

This vulnerability allows local attackers to escalate privileges on affected installations of Schneider Electric Easergy Studio. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the InitializeChannel method. 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 escalate privileges and execute arbitrary code in the context of SYSTEM.
