Active Directory Vulnerabilities In Microsoft Windows

These vulnerabilities need to be taken seriously, due to the factor that if they are exploited, a DoS attack may take place.

The two vulnerabilities located in Microsoft Windows are:

1. A Memory leak error which exists in the Active Directory LDAP service. It could be exploited in order to hang an affected system. This may occur via specially tampered with LDAP or LDAPS requests, which need to consist of exact OID filters.
2. An error that exists within the Active Directory LDAP service. If this is exploited, the chances are that it may trigger the invalid memory and attackers could then execute arbitrary code. This execution of arbitrary code takes place via specially tampered with LDAP or LDAPS requests.

A malicious character with the correct computer skills will be able to take complete and utter control of an infiltrated system. He will also be able to view, change, modify, create or delete whatever he wishes.

These vulnerabilities were reported in implementations of Active Directory on the Microsoft Windows 2000 Server, Windows Server 2003 as well as the Active Directory Application Mode (ADAM), when it is installed on Windows XP Professional as well as Windows Server 2003.
