**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is uninitialized memory and kernel memory - unintentional read access to memory contents in kernel space from a user mode process.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** A domain user could use this vulnerability to elevate privileges to SYSTEM assigned integrity level.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** The authentication feature could be bypassed as this vulnerability allows impersonation.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker who successfully exploited this vulnerability could gain specific limited SYSTEM privileges.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could bypass Secure Boot to run unauthorized code. To be successful the attacker would need either physical access or administrator privileges.

**How could an attacker exploit this vulnerability?** An unauthenticated attacker could perform a man-in-the-middle network exploit to downgrade a client's encryption to the RC4-md4 cypher, followed by cracking the user's cypher key. The attacker could then compromise the user's Kerberos session key to elevate privileges.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, an attacker on the same subnet as the target system would need to send a specially crafted packet to a server configured as a Network Load Balancing cluster host.

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors might be helpful in your situation: Only systems with the IKE and AuthIP IPsec Keying Modules running are vulnerable to this attack. You can run either of the following commands to check the running status of this service: PS: C:\> Get-Service Ikeext * OR Cmd: C:\> sc query ikeext This mitigation could have negative affects on your IPSec functionality. Microsoft strongly recommends updating your system with the latest Windows security updates.
