{"id":"GHSA-qc36-q22q-cjw3","summary":"SMTP command injection in lettre","details":"### Impact\n\nAffected versions of lettre allowed SMTP command injection through an attacker's controlled message body. The module for escaping lines starting with a period wouldn't catch a period that was placed after a double CRLF sequence, allowing the attacker to end the current message and write arbitrary SMTP commands after it.\n\n### Fix\n\nThe flaw is fixed by correctly handling consecutive CRLF sequences.\n\n### References\n\n* [RUSTSEC-2021-0069](https://rustsec.org/advisories/RUSTSEC-2021-0069.html)\n\n\n\n","aliases":["CVE-2021-38189","RUSTSEC-2021-0069"],"modified":"2023-11-08T04:06:25.799670Z","published":"2021-07-12T17:03:27Z","database_specific":{"nvd_published_at":"2021-08-08T06:15:00Z","cwe_ids":["CWE-147"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2021-06-01T20:41:39Z"},"references":[{"type":"WEB","url":"https://github.com/lettre/lettre/security/advisories/GHSA-qc36-q22q-cjw3"},{"type":"WEB","url":"https://github.com/lettre/lettre/pull/627/commits/93458d01fed0ec81c0e7b4e98e6f35961356fae2"},{"type":"WEB","url":"https://github.com/lettre/lettre/commit/8bfc20506cc5e098fe6eb3d1cafe3bea791215ce"},{"type":"PACKAGE","url":"https://github.com/lettre/lettre"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2021-0069.html"}],"affected":[{"package":{"name":"lettre","ecosystem":"crates.io","purl":"pkg:cargo/lettre"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.7.0"},{"fixed":"0.9.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/07/GHSA-qc36-q22q-cjw3/GHSA-qc36-q22q-cjw3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
