Описание
A flaw was found in the LDAP storage provider of Keycloak, which is used to federate user identities from external directories. The issue occurs when a delegated administrator performs a search using a specific LDAP entry Distinguished Name (DN). Due to missing validation, the system allows lookups for users located outside the configured search boundary, leading to the disclosure of account information from unauthorized parts of the directory and unintended importing of those users into local storage.
Отчет
The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that it requires the attacker to have delegated administrative privileges. Successful exploitation allows an attacker to disclose user account details from unauthorized LDAP OUs and cause unintended user imports into the local database. The vulnerability's root cause is the lack of validation to ensure that a requested LDAP Distinguished Name falls within the provider's configured search boundary.
