CVE-2021-37935Network attack vector

LDAP domain disclosure via login page parameter

Published Dec 10, 2021 · Updated Aug 4, 2024

Information disclosure in Huntflow Enterprise before 3.10.4 allows remote attackers to learn the configured LDAP server domain via the login page. The /account/login page embeds the LDAP domain in the isLdap JavaScript parameter, exposing it in HTML returned without authentication. Any remote requester can retrieve the page; the bounded impact is disclosure of LDAP infrastructure naming information without integrity or availability effects.
