To exploit this vulnerability, the attacker must have valid credentials on the Windows system. This vulnerability is due to incorrect handling of directory paths at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path on the system, which can cause a malicious DLL file to be loaded when the application starts. A successful exploit could allow an attacker with normal user privileges to execute arbitrary code on the affected system with the privileges of another user’s account."},{"lang":"es","value":"Una vulnerabilidad en Cisco Packet Tracer para Windows, podría permitir a un atacante local autenticado llevar a cabo un ataque de inyección DLL en un dispositivo afectado. Para explotar esta vulnerabilidad, el atacante debe tener credenciales válidas en el sistema Windows. Esta vulnerabilidad es debido al manejo incorrecto de las rutas de directorio en tiempo de ejecución. Un atacante podría explotar esta vulnerabilidad al insertar un archivo de configuración en una ruta específica del sistema, lo que puede causar que se cargue un archivo DLL malicioso cuando se inicie la aplicación.
