**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** An attacker would require access to a low privileged session on the user's device to obtain a JWT (JSON Web Token) which can then be used to craft a long-lived assertion using the Windows Hello for Business Key from the victim's device.

**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.

**Determine if the Print Spooler service is running** Run the following in Windows PowerShell: Get-Service -Name Spooler If the Print Spooler is running or if the service is not set to disabled, select one of the following options to either disable the Print Spooler service, or to Disable inbound remote printing through Group Policy: **Option 1 - Disable the Print Spooler service** If disabling the Print Spooler service is appropriate for your enterprise, use the following PowerShell commands: Stop-Service -Name Spooler -Force Set-Service -Name Spooler -StartupType Disabled **Impact of workaround** Disabling the Print Spooler service disables the ability to print both locally and remotely. **Option 2 - Disable inbound remote printing through Group Policy** You can also configure the settings via Group Policy as follows: Computer Configuration / Administrative Templates / Printers Disable the “Allow Print Spooler to accept client connections:” policy to block remote attacks....

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker must send the user a malicious file and convince them to open it.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

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

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

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

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: The Windows message queuing service, which is a Windows component, needs to be enabled for a system to be exploitable by this vulnerability. This feature can be added via the Control Panel. You can check to see if there is a service running named **Message Queuing** and TCP port 1801 is listening on the machine.
