It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-3870 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2019-3870/ (Markdown: https://insights.sbomify.com/CVE-2019-3870/index.md)","id":"CVE-2019-3870","markdown":"https://insights.sbomify.com/CVE-2019-3870/index.md","name":"CVE-2019-3870","record":{"aliases":["AZL-45057","DEBIAN-CVE-2019-3870","ECHO-f10d-b8a7-46a1","GHSA-xv9q-3jh5-9rrc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Samba AD DC","requires_auth":"low_privilege","summary":"In upgraded Samba AD DC installations, world-writable permissions on critical configuration files allow local attackers to modify data and potentially escalate privileges.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"samba","vendor":"samba"},{"product":"directory_server","vendor":"synology"},{"product":"diskstation_manager","vendor":"synology"},{"product":"router_manager","vendor":"synology"},{"product":"skynas_firmware","vendor":"synology"},{"product":"vs960hd_firmware","vendor":"synology"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","version":"3.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8.
