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-2021-34801 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- valine (npm): affected all versions up to 1.4.14; no fix listed\n- valine (npm): affected all versions up to 1.4.14; no fix listed\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-2021-34801/ (Markdown: https://insights.sbomify.com/CVE-2021-34801/index.md)","id":"CVE-2021-34801","markdown":"https://insights.sbomify.com/CVE-2021-34801/index.md","name":"CVE-2021-34801","record":{"aliases":["GHSA-p2c4-gxp4-j3xp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Valine comment library","requires_auth":"none","summary":"Remote attackers can cause application outage in Valine by sending a User-Agent header with only product and version.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"valine","vendor":"valine.js"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"description":"Valine 1.4.14 allows remote attackers to cause a denial of service (application outage) by supplying a ua (aka User-Agent) value that only specifies the product and version.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Denial of service in Valine","id":"CVE-2021-34801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Improper Privilege Management in Neo4j Graph Database","id":"CVE-2021-34802"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.4.14"],"package":"valine","purl":null,"source":"GHSA-p2c4-gxp4-j3xp"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.4.14"],"package":"valine","purl":"pkg:npm/valine","source":"GHSA-p2c4-gxp4-j3xp"}],"prev":{"headline":"Sensitive information could be logged","id":"CVE-2021-34800"},"products":["n/a"],"published":"2021-06-16","related":[{"cvss_score":9.6,"headline":"Valine code injection vulnerability","id":"CVE-2022-38545","kev_date_added":null,"published":"2022-09-19"},{"cvss_score":6.1,"headline":"Valine HTML Injection","id":"CVE-2018-19289","kev_date_added":null,"published":"2018-11-15"},{"cvss_score":5.4,"headline":"Cross site scripting in valine","id":"CVE-2020-28847","kev_date_added":null,"published":"2022-04-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can cause application outage in Valine by sending a User-Agent header with only product and version.","url":"https://insights.sbomify.com/CVE-2021-34801/"}
