**According to the CVSS metric confidentiality is High (C:H). What confidential information can be disclosed?** Exploiting this vulnerability will allow an attacker to access resources that are protected by conditional access policies based solely on device compliance state. For more information, please refer to Scenarios for using Conditional Access with Microsoft Intune - Microsoft Intune | Microsoft Docs.

**Are there any special conditions necessary for this vulnerability to be exploitable?** Yes. This vulnerability is only exploitable if the MaxReceiveBuffer LDAP policy is set to a value higher than the default value. Systems with the default value of this policy would not be vulnerable. For more information, please see LDAP policies.

**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 prepare the target environment to improve exploit reliability.

**I am running a supported version of Windows Server. Is my system vulnerable to this issue?** Systems configured to activate both of the following features in Windows Server: CredSSP (Credential Security Service Provider) and RCG (Remote Credential Guard) might be vulnerable to this exploit.

**How could an attacker exploit this vulnerability?** This vulnerability could be exploited if an authenticated user opens a specially crafted file locally or browses to that file on a network share when running an unpatched version of Windows. When the user browses or lists the maliciously crafted file that action could cause a crash of the operating system.

**Are there any special conditions necessary for this vulnerability to be exploitable?** Yes. This vulnerability is only exploitable if the MaxReceiveBuffer LDAP policy is set to a value higher than the default value. Systems with the default value of this policy would not be vulnerable. For more information, please see LDAP policies.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by convincing a user to connect a Lightweight Directory Access Protocol (LDAP) client to a malicious LDAP server. When the vulnerability is successfully exploited this could allow the malicious server to gain remote code execution within the LDAP client.

**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 prepare the target environment to improve exploit reliability.

**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 prepare the target environment to improve exploit reliability.

**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 gather information specific to the environment of the targeted component.
