An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-28896 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-2020-28896/ (Markdown: https://insights.sbomify.com/CVE-2020-28896/index.md)","id":"CVE-2020-28896","markdown":"https://insights.sbomify.com/CVE-2020-28896/index.md","name":"CVE-2020-28896","record":{"aliases":["DEBIAN-CVE-2020-28896","DLA-2472-1","GHSA-346p-qx4x-g348","MGASA-2020-0448","OESA-2021-1005","SUSE-SU-2020:14551-1","SUSE-SU-2020:3568-1","SUSE-SU-2020:3632-1","UBUNTU-CVE-2020-28896","USN-4645-1","openSUSE-SU-2020:2128-1","openSUSE-SU-2020:2141-1"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Email client","requires_auth":"none","summary":"Attackers can intercept email authentication credentials via man-in-the-middle attacks due to improper TLS enforcement in Mutt and NeoMutt clients.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"mutt","vendor":"mutt"},{"product":"neomutt","vendor":"neomutt"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid.
