Summary
LDAP filter injection in Zimbra Collaboration Suite 10.1.0 through 10.1.21 allows unauthenticated attackers to alter external LDAP search filters. On domains using search-filter authentication and lazy provisioning, this creates a password oracle for external directory users. Authenticated S/MIME lookups can also return certificates and identity data for unintended directory entries.
