Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
Summary
This vulnerability can be exploited by parsing maliciously crafted project files with Horner Automation Cscape EnvisionRV v4.50.3.1 and prior. The issues result from the lack of proper validation of user-supplied data, which can result in reads and writes past the end of allocated data structures. User interaction is required to exploit this vulnerability as an attacker must trick a valid user to open a malicious HMI project file.

Los problemas son derivados de una falta de comprobaci\u00f3n apropiada de los datos suministrados por el usuario, lo que puede resultar en lecturas y escrituras m\u00e1s all\u00e1 del final de las estructuras de datos asignadas. Es requerida una interacci\u00f3n del usuario para explotar esta vulnerabilidad, ya que un atacante debe enga\u00f1ar a un usuario v\u00e1lido para que abra un archivo de proyecto HMI malicioso"
