The vulnerability exists within the \"Repair\" (settings -> troubleshooting -> repair) feature, which attempts to delete a file in the current user's AppData directory as NT AUTHORITY\\SYSTEM. A low-privileged user can make a pseudo-symlink and a junction folder and point to a file on the system. This can provide a low-privileged user an Elevation of Privilege to win a race-condition which will re-create the system files and make Windows callback to a specially-crafted file which could be used to launch a privileged shell instance.\n\nThis issue affects Avast Antivirus prior to 24.2."},{"lang":"es","value":"Un archivo con enlace simbólico al que se accede a través de la función de reparación en Avast Antivirus <24.2 en Windows puede permitir al usuario elevar privilegios para eliminar archivos arbitrarios o ejecutar procesos como NT AUTHORITY\\SYSTEM. La vulnerabilidad existe dentro de la función \"Reparación\" (configuración -> solución de problemas -> reparación), que intenta eliminar un archivo en el directorio AppData del usuario actual como NT AUTHORITY\\SYSTEM. Un usuario con pocos privilegios puede crear un pseudoenlace simbólico y una carpeta de unión y apuntar a un archivo en el sistema. Esto puede proporcionar a un usuario con pocos privilegios una elevación de permisos para ganar una condición de ejecución que recreará los archivos del sistema y realizará una devolución de llamada de Windows a un archivo especialmente manipulado que podría usarse para iniciar una instancia de shell privilegiada.
