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-2019-18928 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2019-18928/ (Markdown: https://insights.sbomify.com/CVE-2019-18928/index.md)","id":"CVE-2019-18928","markdown":"https://insights.sbomify.com/CVE-2019-18928/index.md","name":"CVE-2019-18928","record":{"aliases":["CLSA-2025-1738170525","DEBIAN-CVE-2019-18928","GHSA-mpmx-j2j3-253q","UBUNTU-CVE-2019-18928"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cyrus IMAP server","requires_auth":"none","summary":"Attackers can escalate privileges by exploiting connection reuse in Cyrus IMAP, allowing HTTP requests to inherit authentication contexts from previous requests.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"imap","vendor":"cyrus"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request may be interpreted in the authentication context of an unrelated previous request that arrived over the same connection.","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":"Auth bypass in n/a","id":"CVE-2019-18928","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora"],"type":"auth_bypass","year":"2019"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2019-18929"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2019-18926"},"products":["n/a"],"published":"2019-11-15","related":[{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2017-14230","kev_date_added":null,"published":"2017-09-10"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2021-33582","kev_date_added":null,"published":"2021-09-01"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2015-8076","kev_date_added":null,"published":"2015-12-03"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2015-8077","kev_date_added":null,"published":"2015-12-03"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2015-8078","kev_date_added":null,"published":"2015-12-03"},{"cvss_score":4.3,"headline":"Information disclosure in Cyrus IMAP","id":"CVE-2026-61911","kev_date_added":null,"published":"2026-09-09"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can escalate privileges by exploiting connection reuse in Cyrus IMAP, allowing HTTP requests to inherit authentication contexts from previous requests.","url":"https://insights.sbomify.com/CVE-2019-18928/"}
