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-2020-25018 in the wild and no public exploit code.\n\nAffected product: Envoyproxy Envoy. 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-2020-25018/ (Markdown: https://insights.sbomify.com/CVE-2020-25018/index.md)","id":"CVE-2020-25018","markdown":"https://insights.sbomify.com/CVE-2020-25018/index.md","name":"CVE-2020-25018","record":{"aliases":["GHSA-fwwh-fc9w-9673"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Envoy proxy","requires_auth":"none","summary":"Envoy proxy may fail to parse request URLs requiring host canonicalization, potentially leading to service disruption.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"envoy","vendor":"envoyproxy"}],"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":[],"description":"Envoy master between 2d69e30 and 3b5acb2 may fail to parse request URL that requires host canonicalization.","ecosystems":[],"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":"Other in n/a","id":"CVE-2020-25018","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"envoyproxy:envoy","products":["envoyproxy:envoy"],"type":"other","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Open redirect in n/a","id":"CVE-2020-25019"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2020-25017"},"products":["n/a"],"published":"2020-10-01","related":[{"cvss_score":10,"headline":"Trivial authentication bypass in Envoy","id":"CVE-2022-29226","kev_date_added":null,"published":"2022-06-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-18801","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2019-18802","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":8.8,"headline":"Information disclosure in n/a","id":"CVE-2020-35470","kev_date_added":null,"published":"2020-12-15"},{"cvss_score":8.6,"headline":"Envoy ext auth can be bypassed when Proxy protocol filter sets invalid UTF-8 metadata","id":"CVE-2024-23324","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":8.6,"headline":"Envoy vulnerable to OAuth2 credentials exploit with permanent validity","id":"CVE-2023-35941","kev_date_added":null,"published":"2023-07-25"},{"cvss_score":8.6,"headline":"Incorrect handling of H2 GOAWAY + SETTINGS frames","id":"CVE-2021-39162","kev_date_added":null,"published":"2021-09-09"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Envoy proxy may fail to parse request URLs requiring host canonicalization, potentially leading to service disruption.","url":"https://insights.sbomify.com/CVE-2020-25018/"}
