CVE-2017-8028

En Pivotal Spring-LDAP en versiones 1.3.0 - 2.3.1, al conectarse a algunos servidores LDAP, cuando no se enlazan atributos adicionales y cuando se emplea LDAP BindAuthenticator con org.springframework.ldap.core.support.DefaultTlsDirContextAuthenticationStrategy como la estrategia de autenticación y configurando userSearch, se permite la autenticación con una contraseña arbitraria cuando el nombre de usuario es correcto. Esto ocurre porque algunos fabricantes LDAP requieren una operación explícita para que el enlace LDAP tenga efecto.

A vulnerability was found in spring-ldap that allows an attacker to authenticate with an arbitrary password. When spring-ldap connected to some LDAP servers, when no additional attributes are bound, when using LDAP BindAuthenticator with org.springframework.ldap.core.support.DefaultTlsDirContextAuthenticationStrategy as the authentication strategy, and when setting userSearch, authentication is allowed with an arbitrary password when the username is correct.
