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-2020-7046 in the wild and no public exploit code.\n\nAffected product: Dovecot Dovecot. 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-2020-7046/ (Markdown: https://insights.sbomify.com/CVE-2020-7046/index.md)","id":"CVE-2020-7046","markdown":"https://insights.sbomify.com/CVE-2020-7046/index.md","name":"CVE-2020-7046","record":{"aliases":["ALPINE-CVE-2020-7046","GHSA-xxqf-cf9x-9rwq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Dovecot mail server","requires_auth":"none","summary":"An attacker can cause a denial of service in Dovecot by sending truncated UTF-8 data, triggering an infinite loop in the submission-login service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dovecot","vendor":"dovecot"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AC:L/AV:N/A:H/C:N/I:N/PR:N/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"lib-smtp in submission-login and lmtp in Dovecot 2.3.9 before 2.3.9.3 mishandles truncated UTF-8 data in command parameters, as demonstrated by the unauthenticated triggering of a submission-login infinite loop.","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 n/a","id":"CVE-2020-7046","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dovecot:dovecot","products":["dovecot:dovecot","fedoraproject:fedora"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":5,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2020-7047"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2020-7045"},"products":["n/a"],"published":"2020-02-12","related":[{"cvss_score":7.7,"headline":"Auth bypass in OX Dovecot Pro","id":"CVE-2026-24031","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Denial of service in OX Dovecot Pro","id":"CVE-2025-59032","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Denial of service in OX Dovecot Pro","id":"CVE-2026-27858","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2021-29157","kev_date_added":null,"published":"2021-06-28"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2020-10957","kev_date_added":null,"published":"2020-05-18"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2019-11494","kev_date_added":null,"published":"2019-05-08"}],"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":["n/a"]},"summary":"An attacker can cause a denial of service in Dovecot by sending truncated UTF-8 data, triggering an infinite loop in the submission-login service.","url":"https://insights.sbomify.com/CVE-2020-7046/"}
