CVE-2022-2232Network attack vector

Username disclosure via unescaped LDAP identifier

Published Nov 14, 2024 · Updated Nov 14, 2024

LDAP injection in Red Hat Single Sign-On 7 allows remote attackers to disclose existing usernames through the username form. LDAPOperationManager.getFilterById inserts the submitted identifier into an LDAP filter without escaping special characters, so wildcard input changes the lookup. Exposure requires LDAP federation with UUID LDAP Attribute set to a nonstandard value rather than entryUUID, objectGUID, or nsuniqueid.
