What it is

Networknt light-4j from 2.1.5 before 2.4.0 contains an authentication bypass vulnerability in BasicAuthHandler that allows unauthenticated attackers to log in as LDAP/AD-delegated users. Attackers can send a Basic Authorization header with a known username and empty password, triggering an unauthenticated LDAP bind that is accepted as successful authentication.
