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-2020-28247 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- lettre (crates.io): affected from 0.7.0; fixed in 0.7.1, 0.8.4, 0.9.5, 0.10.0-alpha.4\n- lettre (crates.io): affected from 0.7.0; fixed in 0.7.1\n- lettre (crates.io): affected from 0.7.0; fixed in 0.7.1\n- lettre (crates.io): affected from 0.8.0; fixed in 0.8.4\n- lettre (crates.io): affected from 0.8.0; fixed in 0.8.4\n- lettre (crates.io): affected from 0.9.0; fixed in 0.9.5\n- lettre (crates.io): affected from 0.9.0; fixed in 0.9.5\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-2020-28247/ (Markdown: https://insights.sbomify.com/CVE-2020-28247/index.md)","id":"CVE-2020-28247","markdown":"https://insights.sbomify.com/CVE-2020-28247/index.md","name":"CVE-2020-28247","record":{"aliases":["GHSA-vc2p-r46x-m3vx","RUSTSEC-2020-0069"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust email library","requires_auth":"none","summary":"Attackers can inject arbitrary sendmail options in the lettre Rust library, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lettre","vendor":"lettre"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"The lettre library through 0.10.0-alpha for Rust allows arbitrary sendmail option injection via transport/sendmail/mod.rs.","ecosystems":["crates.io"],"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":"Argument injection in lettre","id":"CVE-2020-28247","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"command_injection","year":"2020"},"n_packages":7,"n_references":3,"next":{"headline":"Integer Overflow in png-img","id":"CVE-2020-28248"},"packages":[{"ecosystem":"crates.io","fixed":["0.7.1","0.8.4","0.9.5","0.10.0-alpha.4"],"introduced":["0.7.0","0.8.0","0.9.0","0.10.0-alpha.1"],"last_affected":[],"package":"lettre","purl":"pkg:cargo/lettre","source":"RUSTSEC-2020-0069"},{"ecosystem":"crates.io","fixed":["0.7.1"],"introduced":["0.7.0"],"last_affected":[],"package":"lettre","purl":null,"source":"GHSA-vc2p-r46x-m3vx"},{"ecosystem":"crates.io","fixed":["0.7.1"],"introduced":["0.7.0"],"last_affected":[],"package":"lettre","purl":"pkg:cargo/lettre","source":"GHSA-vc2p-r46x-m3vx"},{"ecosystem":"crates.io","fixed":["0.8.4"],"introduced":["0.8.0"],"last_affected":[],"package":"lettre","purl":null,"source":"GHSA-vc2p-r46x-m3vx"},{"ecosystem":"crates.io","fixed":["0.8.4"],"introduced":["0.8.0"],"last_affected":[],"package":"lettre","purl":"pkg:cargo/lettre","source":"GHSA-vc2p-r46x-m3vx"},{"ecosystem":"crates.io","fixed":["0.9.5"],"introduced":["0.9.0"],"last_affected":[],"package":"lettre","purl":null,"source":"GHSA-vc2p-r46x-m3vx"},{"ecosystem":"crates.io","fixed":["0.9.5"],"introduced":["0.9.0"],"last_affected":[],"package":"lettre","purl":"pkg:cargo/lettre","source":"GHSA-vc2p-r46x-m3vx"}],"prev":{"headline":"Server-Side Template Injection in formio","id":"CVE-2020-28246"},"products":["n/a"],"published":"2020-11-12","related":[{"cvss_score":9.8,"headline":"SMTP command injection in lettre","id":"CVE-2021-38189","kev_date_added":null,"published":"2021-08-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"},{"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject arbitrary sendmail options in the lettre Rust library, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2020-28247/"}
