An issue was discovered in atillk64.sys in AMD ATI Diagnostics Hardware Abstraction Sys/Overclocking Utility 5.11.9.0. The vulnerable driver exposes a wrmsr instruction and does not properly filter the Model Specific Register (MSR). Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges. Se ha detectado un problema en la biblioteca atillk64.sys en AMD ATI Diagnostics Hardware Abstraction Sys/Overclocking Utility versión 5.11.9.0. El controlador vulnerable expone una instrucción wrmsr y no filtra apropiadamente el Model Specific Register (MSR). • https://github.com/fireeye/Vulnerability-Disclosures/blob/master/FEYE-2019-0015/FEYE-2019-0015.md •

AMD ATI atillk64.sys 5.11.9.0 allows low-privileged users to interact directly with physical memory by calling one of several driver routines that map physical memory into the virtual address space of the calling process. This could enable low-privileged users to achieve NT AUTHORITY\SYSTEM privileges via a DeviceIoControl call associated with MmMapIoSpace, IoAllocateMdl, MmBuildMdlForNonPagedPool, or MmMapLockedPages. AMD ATI atillk64.sys versión 5.11.9.0, permite a usuarios poco privilegiados interactuar directamente con la memoria física al llamar a una de las varias rutinas de controladores que asignan la memoria física al espacio de direcciones virtuales del proceso de llamada. Esto podría permitir a usuarios pocos privilegiados alcanzar los privilegios NT AUTHORITY\SYSTEM por medio de una llamada de DeviceIoControl asociada con MmMapIoSpace, IoAllocateMdl, MmBuildMdlForNonPagedPool, o MmMapLockedPages. • https://eclypsium.com/2019/11/12/mother-of-all-drivers https://h0mbre.github.io/atillk64_exploit • CWE-862: Missing Authorization •
