| CVE-2026-18922 | Cri | 0.64 | 9.8 | — | Sep 7, 2026 | A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL… | ||
| CVE-2026-18453 | Hig | 0.49 | 7.5 | — | Sep 7, 2026 | A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control,… | ||
| CVE-2026-76560 | Hig | 0.49 | 7.5 | — | Sep 7, 2026 | A flaw was found in 389 Directory Server.

| CVE-2022-0918 | Hig | 0.49 | 7.5 | 0.06 | Mar 16, 2022 | A vulnerability was discovered in the 389 Directory Server that allows an unauthenticated attacker with network access to the LDAP port to cause a denial of service. The denial of service is triggered by a single message sent over a TCP connection, no bind or other… | ||
| CVE-2015-1854 | Hig | 0.49 | 7.5 | 0.02 | Sep 19, 2017 | 389 Directory Server before 1.3.3.10 allows attackers to bypass intended access restrictions and modify directory entries via a crafted ldapmodrdn call. | ||
| CVE-2026-19404 | Med | 0.42 | 6.5 | 0.00 | Aug 10, 2026 | A flaw was found in 389 Directory Server. The CleanAllRUV and Abort CleanAllRUV replication-maintenance extended operations perform no authorization check, allowing an unauthenticated remote attacker to invoke them when nsslapd-allow-anonymous-access is enabled (the default), or… | ||
| CVE-2024-6237 | Med | 0.42 | 6.5 | 0.01 | Jul 9, 2024 | A flaw was found in the 389 Directory Server. This flaw allows an unauthenticated user to cause a systematic server crash while sending a specific extended search request, leading to a denial of service. | ||
| CVE-2022-0996 | Med | 0.42 | 6.5 | 0.02 | Mar 23, 2022 | A vulnerability was found in the 389 Directory Server that allows expired passwords to access the database to cause improper authentication. | ||
| CVE-2026-11788 | Med | 0.38 | 5.9 | 0.01 | Jun 9, 2026 | A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure. | ||
| CVE-2011-0704 | Med | 0.38 | 5.9 | 0.01 | May 4, 2018 | 389 Directory Server 1.2.7.5, when built with mozldap, allows remote attackers to cause a denial of service (replica crash) by sending an empty modify request. | ||
| CVE-2026-18651 | Med | 0.35 | 5.4 | 0.00 | Aug 3, 2026 | A flaw was found in 389 Directory Server. During SASL PLAIN authentication, the server installs connection-level bind credentials before performing the account-lock check. If the account is subsequently found to be locked, the bind is reported as failed to the client, but the… | ||
| CVE-2026-11791 | Med | 0.33 | 5.0 | 0.00 | Jun 18, 2026 | A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator… | ||
| CVE-2026-11793 | Med | 0.32 | 4.9 | 0.00 | Jun 9, 2026 | A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory… | ||
| CVE-2026-11790 | Med | 0.32 | 4.9 | 0.00 | Jun 9, 2026 | A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption… | ||
| CVE-2026-15041 | Low | 0.24 | 3.7 | 0.00 | Jul 8, 2026 | A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to… | ||
| CVE-2015-3230 | 0.00 | — | 0.03 | Oct 29, 2015 | 389 Directory Server (formerly Fedora Directory Server) before 1.3.3.12 does not enforce the nsSSL3Ciphers preference when creating an sslSocket, which allows remote attackers to have unspecified impact by requesting to use a disabled cipher. | |||
| CVE-2012-2678 | 0.00 | — | 0.01 | Jul 3, 2012 | 389 Directory Server before 1.2.11.6 (aka Red Hat Directory Server before 8.2.10-3), after the password for a LDAP user has been changed and before the server has been reset, allows remote attackers to read the plaintext password via the unhashed#user#password attribute. | |||
| CVE-2012-0833 | 0.00 | — | 0.01 | Jul 3, 2012 | The acllas__handle_group_entry function in servers/plugins/acl/acllas.c in 389 Directory Server before 1.2.10 does not properly handled access control instructions (ACIs) that use certificate groups, which allows remote authenticated LDAP users with a certificate group to cause… |
