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-2020-12604 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- envoy (Bitnami): affected all versions; fixed in 1.12.5, 1.13.3, 1.14.3\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-2020-12604/ (Markdown: https://insights.sbomify.com/CVE-2020-12604/index.md)","id":"CVE-2020-12604","markdown":"https://insights.sbomify.com/CVE-2020-12604/index.md","name":"CVE-2020-12604","record":{"aliases":["BIT-envoy-2020-12604","GHSA-8hf8-8gvw-ggvx"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Envoy proxy","requires_auth":"none","summary":"An attacker can cause excessive memory consumption in Envoy by sending large HTTP/2 payloads without consuming the stream, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"Envoy version 1.14.2, 1.13.2, 1.12.4 or earlier is susceptible to increased memory usage in the case where an HTTP/2 client requests a large payload but does not send enough window updates to consume the entire stream and does not reset the stream.","ecosystems":["Bitnami"],"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 n/a","id":"CVE-2020-12604","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"envoyproxy:envoy","products":["envoyproxy:envoy"],"type":"denial_of_service","year":"2020"},"n_packages":1,"n_references":2,"next":{"headline":"Envoy version 1.14.2, 1.13.2, 1.12.4 or earlier may consume excessive amounts of memory when processing HTTP/1.1 headers with long field nam","id":"CVE-2020-12605"},"packages":[{"ecosystem":"Bitnami","fixed":["1.12.5","1.13.3","1.14.3"],"introduced":["0","1.13.2","1.14.2"],"last_affected":[],"package":"envoy","purl":"pkg:bitnami/envoy","source":"BIT-envoy-2020-12604"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-12603"},"products":["n/a"],"published":"2020-07-01","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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":["n/a"]},"summary":"An attacker can cause excessive memory consumption in Envoy by sending large HTTP/2 payloads without consuming the stream, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2020-12604/"}
