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.
