Additionally, when the product is installed, two scheduled tasks are created on the machine, SDMsgUpdate (Local) and SDMsgUpdate (TE). The scheduled tasks run in the context of the user who installed the product. Both scheduled tasks attempt to run the same binary, C:\\SmartDraw 2020\\Messages\\SDNotify.exe. The folder Messages doesn't exist by default and (by extension) neither does SDNotify.exe. Due to the weak folder permissions, these can be created by any user. A malicious actor can therefore create a malicious SDNotify.exe binary, and have it automatically run, whenever the user who installed the product logs on to the machine. The malicious SDNotify.exe could, for example, create a new local administrator account on the machine."}, {"lang": "es", "value": "En SmartDraw versi\u00f3n 2020 27.0.0.0, el instalador otorga permisos de escritura heredados al grupo Authenticated Users en la carpeta de instalaci\u00f3n de SmartDraw 2020.

La carpeta Messages no existe por defecto y (por extensi\u00f3n) tampoco el archivo SDNotify.exe. Debido a los permisos d\u00e9biles de la carpeta, estos pueden ser creados por cualquier usuario. Por lo tanto, un actor malicioso puede crear un binario SDNotify.exe malicioso y hacer que se ejecute autom\u00e1ticamente, siempre y cuando el usuario que instal\u00f3 el producto se conecte a la m\u00e1quina.
