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.",null,[11],{"_key":12,"id":12,"name":13,"description":14,"type":15,"status":16,"abstraction":17,"likelihood_of_exploit":18,"capec":19},"CWE-78","Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')","The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.","weakness","Stable","Base","High",[20,24,28,32,36],{"id":21,"name":22,"techniques":23},"CAPEC-108","Command Line Execution through SQL Injection",[],{"id":25,"name":26,"techniques":27},"CAPEC-15","Command Delimiters",[],{"id":29,"name":30,"techniques":31},"CAPEC-43","Exploiting Multiple Input Interpretation Layers",[],{"id":33,"name":34,"techniques":35},"CAPEC-6","Argument Injection",[],{"id":37,"name":38,"techniques":39},"CAPEC-88","OS Command Injection",[],[],[],[],[44,46,48],{"_key":45},"DEBIAN-CVE-2026-4408",{"_key":47},"UBUNTU-CVE-2026-4408",{"_key":49},"USN-8306-1",[],[],"2026-05-28T07:25:27.169Z","Undergoing Analysis",{"cisa_kev":55,"cisa_ransomware":55,"cisa_vendor":9,"epss_severity":56,"epss_score":57,"severity":58,"severity_score":59,"severity_version":60,"severity_source":61,"severity_vector":62,"severity_status":53},false,"low",0.00234,"critical",9,"v3.1","cve.org","CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H",[64,71,76],{"url":65,"sources":66,"tags":68},"https://access.redhat.com/security/cve/CVE-2026-4408",[61,67],"nvd",[69,70],"VDB Entry","X Refsource REDHAT",{"url":72,"sources":73,"tags":74},"https://bugzilla.redhat.com/show_bug.cgi?id=2479762",[61,67],[75,70],"Issue Tracking",{"url":77,"sources":78,"tags":79},"https://bugzilla.samba.org/show_bug.cgi?id=16034",[61,67],[],[],{"date":82,"score":57,"percentile":83},"2026-05-28",0.4635,[85],{"date":82,"score":57,"percentile":83},[87,92],{"source":61,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":88,"cvss_v4_0":9},{"baseScore":59,"baseSeverity":89,"vectorString":62,"impactScore":90,"exploitabilityScore":91},"CRITICAL",10,5.6,{"source":67,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":93,"cvss_v4_0":9},{"baseScore":59,"baseSeverity":89,"vectorString":62,"impactScore":90,"exploitabilityScore":91},[]]
