"value": "The Windows Logon installer prior to 4.1.2 did not properly validate file installation paths. This allows an attacker with local user privileges to coerce the installer to write to arbitrary privileged directories. If successful, an attacker can manipulate files used by Windows Logon, cause Denial of Service (DoS) by deleting file(s), or replace system files to potentially achieve elevation of privileges. Note that this can only exploitable during new installations while the installer is running and is not exploitable once installation is finished. Versions 4.1.2 of Windows Logon addresses this issue."

"value": "El instalador de Windows Logon en versiones anteriores a 4.1.2 no valid\u00f3 correctamente las rutas de instalaci\u00f3n de los archivos. Esto permite que un atacante con privilegios de usuario local pueda coaccionar al instalador para que escriba en directorios privilegiados arbitrarios. Si tiene \u00e9xito, un atacante puede manipular los archivos utilizados por Windows Logon, causar una denegaci\u00f3n de servicio (DoS) mediante la eliminaci\u00f3n de archivos o sustituir los archivos del sistema para lograr potencialmente la elevaci\u00f3n de los privilegios. Tenga en cuenta que esto s\u00f3lo se puede explotar durante las nuevas instalaciones mientras el instalador se est\u00e1 ejecutando y no se puede explotar una vez finalizada la instalaci\u00f3n. La versi\u00f3n 4.1.2 de Windows Logon soluciona este problema"
