Applies to:
Oracle Internet Directory - Version 10.1.2 to 10.1.4 [Release 10gR2 to 10gR3]Information in this document applies to any platform.
Goal
Two potential issues have been identified with respect to LDAP servers. This document discusses how/whether to correct them in OID
1. "LDAP allows null bases"
Description:
Improperly configured LDAP servers will allow the directory BASE to be set to NULL. This allows information to be culled without any prior knowledge of the directory structure. Coupled with a NULL BIND, an anonymous user can query your LDAP server using a tool such as 'LdapMiner'
Solution: Disable NULL BASE queries on your LDAP server.
Reference the Internet Security Systems article LDAP null base returns information
2. "LDAP allows anonymous binds"
Description:
Improperly configured LDAP servers will allow any user to connect to the server and query for information.
Solution: Disable the NULL bind entry or control the entry with Access Control Lists (ACLs).
Reference the Internet Security Systems article LDAP anonymous access to directory
