The LDAP signing Domain controller: LDAP server signing requirements policy already exists in all supported versions of Windows. Important: The Maupdates, and updates in the foreseeable future, will not change LDAP signing or LDAP channel binding default policies or their registry equivalent on new or existing Active Directory domain controllers. On Mawe are addressing this vulnerability by providing the following options for administrators to harden the configurations for LDAP channel binding on Active Directory domain controllers:ĭomain controller: LDAP server channel binding token requirements Group Policy.Ĭhannel Binding Tokens (CBT) signing events 3039, 3040, and 3041 with event sender Microsoft-Windows-Active Directory_DomainService in the Directory Service event log. Microsoft recommends administrators make the hardening changes described in ADV190023. This vulnerability could allow a man-in-the-middle attacker to successfully forward an authentication request to a Microsoft domain server which has not been configured to require channel binding, signing, or sealing on incoming connections. This can open Active Directory domain controllers to an elevation of privilege vulnerability. A set of unsafe default configurations for LDAP channel binding and LDAP signing exist on Active Directory domain controllers that let LDAP clients communicate with them without enforcing LDAP channel binding and LDAP signing. LDAP channel binding and LDAP signing provide ways to increase the security for communications between LDAP clients and Active Directory domain controllers.
