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-2011-4318 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-2011-4318/ (Markdown: https://insights.sbomify.com/CVE-2011-4318/index.md)","id":"CVE-2011-4318","markdown":"https://insights.sbomify.com/CVE-2011-4318/index.md","name":"CVE-2011-4318","record":{"aliases":["DEBIAN-CVE-2011-4318","GHSA-w2rf-p589-jpp8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Dovecot IMAP server","requires_auth":"none","summary":"Man-in-the-middle attackers can spoof SSL servers in Dovecot when using hostname-based proxying, bypassing certificate validation.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"dovecot","vendor":"dovecot"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Dovecot 2.0.x before 2.0.16, when ssl or starttls is enabled and hostname is used to define the proxy destination, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate for a different hostname.","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":"Security feature bypass in n/a","id":"CVE-2011-4318","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dovecot:dovecot","products":["dovecot:dovecot"],"type":"security_feature_bypass","year":"2011"},"n_packages":0,"n_references":9,"next":{"headline":"Cross-site Scripting vulnerability in i18n translations helper method","id":"CVE-2011-4319"},"packages":[],"prev":{"headline":"Server-side request forgery in n/a","id":"CVE-2011-4317"},"products":["n/a"],"published":"2013-03-07","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":"Denial of service in n/a","id":"CVE-2020-7046","kev_date_added":null,"published":"2020-02-12"},{"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":"2024-08-07","vendors":["n/a"]},"summary":"Man-in-the-middle attackers can spoof SSL servers in Dovecot when using hostname-based proxying, bypassing certificate validation.","url":"https://insights.sbomify.com/CVE-2011-4318/"}
