Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4154 in the wild and no public exploit code.\n\nAffected product: Samba Samba. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-4154/ (Markdown: https://insights.sbomify.com/CVE-2023-4154/index.md)","id":"CVE-2023-4154","markdown":"https://insights.sbomify.com/CVE-2023-4154/index.md","name":"CVE-2023-4154","record":{"aliases":["ALPINE-CVE-2023-4154","AZL-31955","AZL-37026","DEBIAN-CVE-2023-4154","ECHO-366e-1e8f-df2c","GHSA-v5f6-rpxq-xvg8","UBUNTU-CVE-2023-4154"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Samba Active Directory","requires_auth":"low_privilege","summary":"Samba's DirSync flaw allows privileged users and RODCs to access all domain secrets, including passwords, bypassing intended security restrictions.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"samba","vendor":"samba"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Samba: ad dc password exposure to privileged users and rodcs","id":"CVE-2023-4154","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"samba:samba","products":["samba:samba"],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"Sev-es / sev-snp vmgexit double fetch vulnerability","id":"CVE-2023-4155"},"packages":[],"prev":{"headline":"BAN Users \u003c= 1.5.3 - Missing Authorization to Authenticated (Subscriber+) Settings Update \u0026 Privilege Escalation","id":"CVE-2023-4153"},"products":["Fedora","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Storage 3","samba"],"published":"2023-11-07","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2012-1182","kev_date_added":null,"published":"2012-04-10"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-2446","kev_date_added":null,"published":"2007-05-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0600","kev_date_added":null,"published":"2004-07-23"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-1999-0810","kev_date_added":null,"published":"2000-01-04"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-1999-0182","kev_date_added":null,"published":"1999-09-29"},{"cvss_score":9.8,"headline":"Weak cryptography in Samba","id":"CVE-2022-45141","kev_date_added":null,"published":"2023-03-06"},{"cvss_score":9.3,"headline":"Other in n/a","id":"CVE-2009-1886","kev_date_added":null,"published":"2009-06-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Fedora","Red Hat","n/a"]},"summary":"Samba's DirSync flaw allows privileged users and RODCs to access all domain secrets, including passwords, bypassing intended security restrictions.","url":"https://insights.sbomify.com/CVE-2023-4154/"}
