An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-25719 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2020-25719/ (Markdown: https://insights.sbomify.com/CVE-2020-25719/index.md)","id":"CVE-2020-25719","markdown":"https://insights.sbomify.com/CVE-2020-25719/index.md","name":"CVE-2020-25719","record":{"aliases":["ALPINE-CVE-2020-25719","ALSA-2021:5142","AZL-36995","AZL-8704","DEBIAN-CVE-2020-25719","ECHO-a223-d6f2-08e2","GHSA-882h-52g4-fpjv","RHSA-2021:5142","RHSA-2021:5195","RHSA-2022:0007","RHSA-2022:0076","RLSA-2021:5142","UBUNTU-CVE-2020-25719"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Samba Active Directory","requires_auth":"high_privilege","summary":"Samba AD DC allows domain compromise via Kerberos name-based authentication flaws when PAC is not strictly required.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems_eus","vendor":"redhat"},{"product":"enterprise_linux_for_power_big_endian","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian_eus","vendor":"redhat"},{"product":"enterprise_linux_for_scientific_computing","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_server_update_services_for_sap_solutions","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"samba","vendor":"samba"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication.
