An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-14312 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-2020-14312/ (Markdown: https://insights.sbomify.com/CVE-2020-14312/index.md)","id":"CVE-2020-14312","markdown":"https://insights.sbomify.com/CVE-2020-14312/index.md","name":"CVE-2020-14312","record":{"aliases":["DEBIAN-CVE-2020-14312","GHSA-xr95-5hhj-crp6","MGASA-2020-0310","OESA-2022-1821","UBUNTU-CVE-2020-14312","openSUSE-SU-2024:11653-1"],"analysis":{"component_type":"server_software","fix_type":"configuration_change","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS forwarder","requires_auth":"none","summary":"Default dnsmasq configuration allows remote attackers to use it as an open resolver for DDoS attacks against other systems.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A flaw was found in the default configuration of dnsmasq, as shipped with Fedora versions prior to 31 and in all versions Red Hat Enterprise Linux, where it listens on any interface and accepts queries from addresses outside of its local subnet. In particular, the option `local-service` is not enabled. Running dnsmasq in this manner may inadvertently make it an open resolver accessible from any address on the internet.
