An attacker who successfully exploited this vulnerability could take complete control of an affected system. Mitigating Factors for Kernel Local Elevation of Privilege Vulnerability - CVE-2007-1206: An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users. Workarounds for Kernel Local Elevation of Privilege Vulnerability - CVE-2007-1206: We have not identified any workarounds for this vulnerability. FAQ for Kernel Local Elevation of Privilege Vulnerability - CVE-2007-1206: What is the scope of the vulnerability? A privilege elevation vulnerability exists in Windows Kernel because of incorrect permissions on a mapped memory segment. An attacker who successfully exploited this vulnerability could take complete control of an affected system. To attempt to exploit the vulnerability, an attacker must be able to log on locally to the system. What causes the vulnerability? The Windows Kernel allows for incorrect permissions to be used when mapping a memory segment. What might an attacker use the vulnerability to do? An attacker who successfully exploited this vulnerability could run arbitrary code on a user s system with elevated privileges. This could allow an attacker to take complete control of the affected system. How could an attacker exploit the vulnerability? To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and gain complete control over the affected system. What systems are primarily at risk from the vulnerability? Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this. Could the vulnerability be exploited over the Internet? No. An attacker must be able to log on to the specific system that is targeted for attack. An attacker cannot load and run a program remotely by using this vulnerability. What does the update do? The update removes the vulnerability by modifying the way that the Windows Kernel validates permissions during memory mapping. When this security bulletin was issued, had this vulnerability been publicly disclosed? No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued. When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
