This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence.",null,[],[],[],[14],{"_key":15},"CVE-2023-4154",[17],{"_key":18},"USN-6425-1",[],[21,23],{"_key":22},"USN-6425-3",{"_key":18},"2023-10-10T00:00:00Z","2026-04-22T14:11:52.643330Z",{"cisa_kev":27,"cisa_ransomware":27,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[29,35,39,44,48],{"url":30,"sources":31,"tags":33},"https://ubuntu.com/security/CVE-2023-4154",[32],"osv_ubuntu",[34],"REPORT",{"url":36,"sources":37,"tags":38},"https://www.samba.org/samba/security/CVE-2023-4154.html",[32],[34],{"url":40,"sources":41,"tags":42},"https://ubuntu.com/security/notices/USN-6425-1",[32],[43],"Advisory",{"url":45,"sources":46,"tags":47},"https://ubuntu.com/security/notices/USN-6425-3",[32],[43],{"url":49,"sources":50,"tags":51},"https://www.cve.org/CVERecord?id=CVE-2023-4154",[32],[34],[],[],[55],{"source":32,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":56,"cvss_v4_0":9},{"baseScore":57,"baseSeverity":9,"vectorString":58,"impactScore":59,"exploitabilityScore":60},6.5,"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N",6,7.2,[62],{"ecosystem":63,"name":64,"vendor":65,"product":64,"cpe_part":9,"purl_type":66,"purl_namespace":65,"purl_name":64,"source":9,"versions":67},"Ubuntu","samba","ubuntu","deb",[68,72,76,79],{"version":69,"is_range":70,"range_type":71,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":73,"is_range":70,"range_type":71,"version_start":9,"version_start_type":9,"version_end":74,"version_end_type":75,"fixed_in":9},"lt2:4_15_13+dfsg_0ubuntu0_20_04_6","2:4.15.13+dfsg-0ubuntu0.20.04.6","excluding",{"version":77,"is_range":70,"range_type":71,"version_start":9,"version_start_type":9,"version_end":78,"version_end_type":75,"fixed_in":9},"lt2:4_15_13+dfsg_0ubuntu1_5","2:4.15.13+dfsg-0ubuntu1.5",{"version":80,"is_range":70,"range_type":71,"version_start":9,"version_start_type":9,"version_end":81,"version_end_type":75,"fixed_in":9},"lt2:4_18_6+dfsg_1ubuntu2_1","2:4.18.6+dfsg-1ubuntu2.1"]
