CVE-2026-19843— 389-ds-base: 389-ds-base: command injection via unescaped ldap dn in cockpit 389 console ldap editor

Quick assessment

Affected
Red Hat Red Hat Directory Server 11.7 E4S for RHEL 8
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

389-ds-base 中发现一个缺陷。 Cockpit 389 控制台的 LDAP 编辑器在构造 命令时，将 LDAP 条目的可分辨名称（DN）直接嵌入到 Shell 命令字符串中，且未进行适当的转义。 拥有目录条目创建或重命名委托权限的 LDAP 用户可以构造一个包含 Shell 元字符（metacharacters）的恶意 DN。当 Cockpit 管理员随后在 389 控制台中查看该条目时，嵌入的 Shell 命令将在目录服务器主机上以 root 权限执行，从而导致命令执行漏洞。

Vulnerability Title
389-ds-base: 389-ds-base: command injection via unescaped ldap dn in cockpit 389 console ldap editor
Source: CVE Program / CVE List V5
Vulnerability Description
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.
