CVE-2022-31088Network attack vector

LDAP data enumeration via unescaped login filter

Published Jun 27, 2022 · Updated Apr 23, 2025

LDAP injection in LDAP Account Manager before 8.0 allows remote attackers to enumerate LDAP data through the login username field. The LDAP-search login path substitutes the submitted username for %USER% in its configured LDAP filter without safely restricting filter metacharacters. No account is required, but exposure depends on LDAP search being selected instead of a fixed list; successful probes disclose directory data.
