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-2020-8277 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected from 12.16.3; fixed in 12.19.1, 14.15.1, 15.2.1\n- node-min (Bitnami): affected from 12.16.3; fixed in 12.19.1, 14.15.1, 15.2.1\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-2020-8277/ (Markdown: https://insights.sbomify.com/CVE-2020-8277/index.md)","id":"CVE-2020-8277","markdown":"https://insights.sbomify.com/CVE-2020-8277/index.md","name":"CVE-2020-8277","record":{"aliases":["ALPINE-CVE-2020-8277","AZL-32281","BIT-node-2020-8277","BIT-node-min-2020-8277","CLEANSTART-2026-KV06293","CLEANSTART-2026-LV83462","DEBIAN-CVE-2020-8277","ECHO-f2bd-57d2-fe00","GHSA-m5pg-8h68-j225","OESA-2021-1099","SUSE-SU-2020:3478-1","SUSE-SU-2020:3549-1","openSUSE-SU-2020:2045-1","openSUSE-SU-2020:2092-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js runtime","requires_auth":"none","summary":"An attacker can cause a Denial of Service in Node.js applications by triggering excessive DNS responses, requiring an upgrade to patched versions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"c-ares","vendor":"c-ares_project"},{"product":"fedora","vendor":"fedoraproject"},{"product":"node.js","vendor":"nodejs"},{"product":"blockchain_platform","vendor":"oracle"},{"product":"graalvm","vendor":"oracle"},{"product":"jd_edwards_enterpriseone_tools","vendor":"oracle"},{"product":"mysql_cluster","vendor":"oracle"},{"product":"retail_xstore_point_of_service","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could trigger a Denial of Service in versions \u003c 15.2.1, \u003c 14.15.1, and \u003c 12.19.1 by getting the application to resolve a DNS record with a larger number of responses.
