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-2020-9481 in the wild and no public exploit code.\n\nAffected product: Apache Traffic Server. 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-2020-9481/ (Markdown: https://insights.sbomify.com/CVE-2020-9481/index.md)","id":"CVE-2020-9481","markdown":"https://insights.sbomify.com/CVE-2020-9481/index.md","name":"CVE-2020-9481","record":{"aliases":["DEBIAN-CVE-2020-9481","GHSA-p73f-98x4-6v7q","UBUNTU-CVE-2020-9481"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Traffic Server","requires_auth":"none","summary":"Attackers can cause denial of service in Apache Traffic Server via HTTP/2 slow read attacks, requiring administrators to upgrade the server software.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"traffic_server","vendor":"apache"},{"product":"debian_linux","vendor":"debian"}],"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":"Apache ATS 6.0.0 to 6.2.3, 7.0.0 to 7.1.9, and 8.0.0 to 8.0.6 is vulnerable to a HTTP/2 slow read attack.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in ATS","id":"CVE-2020-9481","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:traffic_server","products":["apache:traffic_server","debian:debian_linux"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Insufficient Session Expiration in Apache NiFi Registry","id":"CVE-2020-9482"},"packages":[],"prev":{"headline":"Improper Authentication in Apache Spark","id":"CVE-2020-9480"},"products":["ATS"],"published":"2020-04-27","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2014-3525","kev_date_added":null,"published":"2014-08-22"},{"cvss_score":9.8,"headline":"heap-buffer-overflow with stats-over-http plugin","id":"CVE-2021-43082","kev_date_added":null,"published":"2021-11-03"},{"cvss_score":9.8,"headline":"Dynamic stack buffer overflow in cachekey plugin","id":"CVE-2021-35474","kev_date_added":null,"published":"2021-06-30"},{"cvss_score":9.8,"headline":"Other in Apache Traffic Server","id":"CVE-2019-17559","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":9.8,"headline":"Other in Apache Traffic Server","id":"CVE-2019-17565","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":9.8,"headline":"Other in Apache Traffic Server","id":"CVE-2020-1944","kev_date_added":null,"published":"2020-03-23"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2014-3624","kev_date_added":null,"published":"2017-10-30"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Apache"]},"summary":"Attackers can cause denial of service in Apache Traffic Server via HTTP/2 slow read attacks, requiring administrators to upgrade the server software.","url":"https://insights.sbomify.com/CVE-2020-9481/"}
