CVE-2022-46337Network attack vector

Authentication bypass via unescaped LDAP username

Published Nov 20, 2023 · Updated Jun 10, 2025

LDAP injection in affected Apache Derby releases allows remote attackers to bypass LDAP authentication with a crafted username. LDAPAuthenticationSchemeImpl.getDNFromUID() inserts the username into an LDAP search filter without escaping metacharacters, allowing input to change the filter predicate. LDAP authentication is required; resulting access can fill disk, run existing executable content, or read and corrupt data when SQL authorization is absent.
