Title: Microsoft Metadirectory Services Remote LDAP Client Administration Vulnerability
Severity: CRITICAL
Description:
A problem has been discovered in Microsoft Metadirectory Services (MMS) that could allow a user of an LDAP client to gain administrative access.
MMS is designed to tie together authentication between several different infrastructures, including databases, exchange directories, and active directories.
MMS allows a remote user with an LDAP client to change data on a vulnerable server. A flaw in authentication design allows the user of the LDAP client to connect to the MMS repository, modify data, change the MMS configuration, and/or replicate the bogus data in other repositories.
This could allow an attacker to gain access to accounts managed by the MMS server, and potentially administrative access on the server or other systems.
Affected Products:
- Microsoft Metadirectory Services 2.2.0
