Command injection in Samba - CVE-2026-4408

Vulnerability identifier: #VU132344

CSH Severity: High

CVSS v4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-4408

CWE-ID: CWE-77

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to command injection in the Samba DCE/RPC SAMR server when invoking a check password script that uses the %u substitution character. A remote attacker can send crafted input that reaches the check password script to execute arbitrary code.

Exploitation requires samba-dcerpcd to be started as a system service on Samba file servers or classic non-AD domain controllers, and requires a configured "check password script" that uses the %u substitution character.
