Description |
|
|
Se ha descubierto una vulnerabilidad en Microsoft Windows XP Professional Service Pack 2, Windows Server 2003, Windows Vista, y Windows Server 2008. La vulnerabilidad reside en un error que permite a las cuentas "NetworkService" y "LocalService" acceder a recursos de otros procesos con los mismos privilegios pero que además tienen la habilidad de aumentar sus privilegios a "LocalSystem". Un atacante local podría aumentar sus privilegios a "LocalSystem" utilizando un proceso de servicio (NetworkService o LocalService) especialmente diseñado para capturar un recurso de un segundo proceso de servicio con la habilidad de aumentar sus privilegios a "LocalSystem". |
