A vulnerability exists in the component RTU500 Scripting interface. When a client connects to a server using TLS, the server presents a certificate. This certificate links a public key to the identity of the service and is signed by a Certification Authority (CA), allowing the client to validate that the remote service can be trusted and is not malicious. If the client does not validate the parameters of the certificate, then attackers could be able to spoof the identity of the service. An attacker could exploit the vulnerability by using faking the identity of a RTU500 device and intercepting the messages initiated via the RTU500 Scripting interface.
Existe una vulnerabilidad en RTU500 Scripting interface. Cuando un cliente se conecta a un servidor mediante TLS, el servidor presenta un certificado. Este certificado vincula una clave pública a la identidad del servicio y está firmado por Certification Authority (CA), lo que permite al cliente validar que se puede confiar en el servicio remoto y que no es malicioso. Si el cliente no valida los parámetros del certificado, los atacantes podrían falsificar la identidad del servicio. Un atacante podría aprovechar la vulnerabilidad falsificando la identidad de un dispositivo RTU500 e interceptando los mensajes iniciados a través de RTU500 Scripting interface.
