!!! Overview
If [{$pagename}] [user-Account-Control Attribute Value] bit is set, the user is not subject to a possibly existing policy regarding the length of password.
This implies the user could have shorter password than it is required or it may even have no password at all, even if empty passwords are not allowed. This property is not visible in the normal GUI tools (Active Directory Users and Computers)!
[user-Account-Control Attribute Value] attribute for an account Gill Bates is set to a decimal value of 544 ([hex] 220). The value is the sum of the individual property flags for the [user-Account-Control Attribute Value] of the User account.
A value of 544 (x220) indicates that the account has the following property flags set / enabled:
* NORMAL_ACCOUNT: decimal 512 (x200)
* PASSWD_NOTREQD: decimal 32 (x20)
Note that the [{$pagename}] property is represented by hex value x20, so any [user-Account-Control Attribute Value] of x20 has the PASSWD_NOTREQD flag set. Some examples of [user-Account-Control Attribute Value], where the [{$pagename}] flag is set are:
* x020 - 032 - [{$pagename}]
* x220 - 514 - Enabled, [{$pagename}]
* x222 - 546 - Enabled, [{$pagename}]
* x40222 - 262690 - Disabled, Smartcard Required, [{$pagename}]
Interestingly, [{$pagename}] does NOT imply there is no [password], only that one is not required. If there is a password then the account cannot be used for an [Anonymous bind].
I have seen where [IDM Vendor Products] or other creation programs set [{$pagename}] to create the user then have failed to remove the flag.
Since Windows Server 2003, by default, [anonymous] [LDAP Messages] other than [Bind Request] are disabled. (Note the distinction [LDAP Messages] other than [Anonymous bind]).
[Anonymous binds] are permitted but, by default, the only [Access] is to the [rootDSE]. This allows [anonymous] [access] to the [rootDSE] as a [Discovery Mechanism] to then allow [Authenticated] binds.
[{$applicationname}] were able to perform a [Anonymous bind] as one of the users listed. (one with a pwdLastSet=0). So as [{$applicationname}] see it, there is no [Vulnerability] to [Microsoft Active Directory], but could a user perform an bind with and empty [password] but using a [DN] of one of these users to access an [application]?
