📋 Description

What actions do customers need to perform to be protected against this vulnerability? This vulnerability affects both LDAP clients and servers running an affected version of Windows listed in the Security Updates table. Customers must apply the latest security update for their Windows version to be protected against this vulnerability.

How could an attacker exploit this vulnerability? A remote unauthenticated attacker who successfully exploited this vulnerability would gain the ability to execute arbitrary code within the context of the LDAP service. However successful exploitation is dependent upon what component is targeted. In the context of exploiting a domain controller for an LDAP server, to be successful an attacker must send specially crafted RPC calls to the target to trigger a lookup of the attacker's domain to be performed in order to be successful. In the context of exploiting an LDAP client application, to be successful an attacker must convince or trick the victim into performing a domain controller lookup for the attacker’s domain or into connecting to a malicious LDAP server. However, unauthenticated RPC calls would not succeed.

Could an attacker leverage inbound RPC tunnels connected to Windows 11 to successfully exploit this vulnerability? Yes, an attacker could use an RPC connection to a domain controller to trigger domain controller lookup operations against the attacker's domain.
