The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device.

La vulnerabilidad se debe a que las firmas digitales del programa no se verifican correctamente durante la ejecuci\u00f3n del comando CLI.
