Microsoft Windows Ancillary Function Driver Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists where the Ancillary Function Driver (afd.sys) improperly validates input passed from user mode to the Windows kernel. The vulnerability could allow an attacker to run code with elevated privileges. A local attacker who successfully exploited this vulnerability could execute arbitrary code and take complete control of an affected system. The attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
