Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-2166 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-2011-2166/ (Markdown: https://insights.sbomify.com/CVE-2011-2166/index.md)","id":"CVE-2011-2166","markdown":"https://insights.sbomify.com/CVE-2011-2166/index.md","name":"CVE-2011-2166","record":{"aliases":["DEBIAN-CVE-2011-2166","GHSA-v9cm-xcfc-8942"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Dovecot IMAP/POP3 server","requires_auth":"low_privilege","summary":"Remote authenticated users can bypass access restrictions in Dovecot by leveraging a script due to ignored user and group configuration settings.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dovecot","vendor":"dovecot"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-16","name":null}],"description":"script-login in Dovecot 2.0.x before 2.0.13 does not follow the user and group configuration settings, which might allow remote authenticated users to bypass intended access restrictions by leveraging a script.","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":"Missing authorization in n/a","id":"CVE-2011-2166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dovecot:dovecot","products":["dovecot:dovecot"],"type":"missing_authorization","year":"2011"},"n_packages":0,"n_references":7,"next":{"headline":"Path traversal in n/a","id":"CVE-2011-2167"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2011-2165"},"products":["n/a"],"published":"2011-05-24","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":"2024-08-06","vendors":["n/a"]},"summary":"Remote authenticated users can bypass access restrictions in Dovecot by leveraging a script due to ignored user and group configuration settings.","url":"https://insights.sbomify.com/CVE-2011-2166/"}
