      "value": "A vulnerability in the loading process of specific DLLs in Cisco Proximity Desktop for Windows could allow an authenticated, local attacker to load a malicious library. 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 placing a malicious DLL file in a specific location on the targeted system. This file will execute when the vulnerable application launches. A successful exploit could allow the attacker to execute arbitrary code on the targeted system with the privileges of another user’s account."

      "value": "Una vulnerabilidad en el proceso de carga de archivos DLL espec\u00edficos en Cisco Proximity Desktop para Windows, podr\u00eda permitir a un atacante local autenticado cargar una biblioteca maliciosa. Para explotar esta vulnerabilidad, el atacante debe tener credenciales v\u00e1lidas en el sistema Windows. Esta vulnerabilidad se debe al manejo incorrecto de las rutas de directorio en tiempo de ejecuci\u00f3n. Un atacante podr\u00eda explotar esta vulnerabilidad colocando un archivo DLL malicioso en una ubicaci\u00f3n espec\u00edfica del sistema apuntado. Este archivo se ejecutar\u00e1 cuando se inicie la aplicaci\u00f3n vulnerable. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante ejecutar c\u00f3digo arbitrario en el sistema objetivo con los privilegios de la cuenta de otro usuario."
