CVE-2026-4408: Openshift Container Platform: işletim sistemi komut enjeksiyonu

Yayın: 28 Mayıs 2026 12:16 · Güncelleme: 6 Kasım 2026 10:19

Açıklama (NVD)

A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service.
