CVE-2012-2678

"389 Directory Server" antes de v1.2.11.6 (también conocido como Red Hat Directory Server antes de v8.2.10-3), cuando la contraseña de un usuario de LDAP ha cambiado y anyes de que el servidor haya sido reiniciado, permite a atacantes remotos leer contraseñas en claro a través del atributo unhashed#user#password.

Red Hat Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol server and command-line utilities for server administration. A flaw was found in the way Red Hat Directory Server handled password changes. If an LDAP user had changed their password, and the directory server had not been restarted since that change, an attacker able to bind to the directory server could obtain the plain text version of that user's password via the "unhashed#user#password" attribute. It was found that when the password for an LDAP user was changed, and audit logging was enabled, the new password was written to the audit log in plain text form. This update introduces a new configuration parameter, "nsslapd-auditlog-logging-hide-unhashed-pw", which when set to "on", prevents Red Hat Directory Server from writing plain text passwords to the audit log. This option can be configured in "/etc/dirsrv/slapd-[ID]/dse.ldif".
