CVE-2022-45801Network attack vector

Authenticated LDAP injection via unsanitized login filter

Published May 1, 2023 · Updated Oct 15, 2024

LDAP injection in Apache StreamPark 1.0.0 through versions before 2.0.0 allows remote authenticated users to alter LDAP queries. The LDAP login path inserts the supplied user identifier into a directory search filter without neutralizing LDAP metacharacters. The flaw is reachable only when LDAP login is enabled and can expose unauthorized query results or modify directory content.
