Description Samuele Negrini 2026-07-31 09:21:15 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

389-ds-base security assessment finding 021 (2026-04-22).

Pre-auth LDAP filter injection in CleanAllRUV status-check extop (OID 2.16.840.1.113730.3.6.8). Handler multisupplier_extop_cleanruv_check_status() in repl_extop.c passes attacker-supplied filter unsanitized to internal cn=config search with replication plugin identity. No auth checks (unlike other replication extops).

With default nsslapd-allow-anonymous-access: on, anonymous bind suffices. Boolean oracle extracts 31 cn=config attributes (replication bind DN, password storage scheme, paths, ACI keywords). Password hashes not extractable via substring.

PoC confirmed: RHEL 7 (389-ds-base-1.3.11.1-5.el7_9), Fedora 42 (389-ds-base-3.1.4-6.fc42).

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N (7.5). Red Hat impact: Moderate.
CWE-90, CWE-306, CWE-20.
