Red Hat Security Advisory: redhat-ds:12 security update
Severity
Important
Notes
Topic: An update for the redhat-ds:12 module is now available for Red Hat Directory Server 12.6 EUS for RHEL 9.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: Red Hat Directory Server is an LDAPv3-compliant directory server. The suite of packages includes the Lightweight Directory Access Protocol (LDAP) server, as well as command-line utilities and Web UI packages for server administration.
Security Fix(es):
* 389-ds-base: 389-ds-base: Command injection via unescaped LDAP DN in Cockpit 389 Console LDAP editor (CVE-2026-19843)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389 Console, the embedded shell command executes with root privileges on the directory server host.

The Cockpit 389 Console\u0027s LDAP editor embeds a raw LDAP entry DN into a double-quoted shell command string executed via Cockpit\u0027s privileged (superuser) channel. LDAP DN syntax does not require escaping of shell metacharacters such as $, (, and ), so a DN crafted with command substitution executes on the host when a more-privileged Cockpit operator subsequently views that entry. This compromises confidentiality, integrity, and availability of the host. Exploitation requires both a delegated LDAP write privilege and a privileged operator viewing the crafted entry; neither precondition alone is sufficient. This issue only affects Red Hat Directory Server deployments that include the Cockpit 389 Console; plain Red Hat Enterprise Linux does not ship this subpackage and is not affected.",
