"value": "A sym-linked file accessed via the repair function in Avast Antivirus <24.2 on Windows may allow user to elevate privilege to delete arbitrary files or run processes as NT AUTHORITY\\SYSTEM.\u00a0The 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\u00a0low-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."

"value": "Un archivo con enlace simb\u00f3lico al que se accede a trav\u00e9s de la funci\u00f3n de reparaci\u00f3n 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 funci\u00f3n \"Reparaci\u00f3n\" (configuraci\u00f3n -> soluci\u00f3n de problemas -> reparaci\u00f3n), 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 simb\u00f3lico y una carpeta de uni\u00f3n y apuntar a un archivo en el sistema. Esto puede proporcionar a un usuario con pocos privilegios una elevaci\u00f3n de permisos para ganar una condici\u00f3n de ejecuci\u00f3n que recrear\u00e1 los archivos del sistema y realizar\u00e1 una devoluci\u00f3n de llamada de Windows a un archivo especialmente manipulado que podr\u00eda usarse para iniciar una instancia de shell privilegiada. Este problema afecta a Avast Antivirus antes de la versi\u00f3n 24.2."
