CVE-2023-1055

Hashed-password disclosure via certificate-decoding process arguments

Published Feb 27, 2023 · Updated Mar 11, 2025

Information disclosure in Red Hat Directory Server 11 and 12 allows local users to read hashed passwords from process arguments. The LDAP Browser passes userPassword, rather than userCertificate, to showCertificate(), which builds a shell command containing the value. A local account can inspect the cockpit-389-ds process list after an administrator browses the affected attribute; the flaw exposes password hashes without modifying directory data.
