{"id":"GHSA-7w4p-72j7-v7c2","summary":"Phar object injection in PHPMailer","details":"PHPMailer versions prior to 6.0.6 and 5.2.27 are vulnerable to an object injection attack by passing phar:// paths into `addAttachment()` and other functions that may receive unfiltered local paths, possibly leading to RCE. See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info on this type of vulnerability. Mitigated by blocking the use of paths containing URL-protocol style prefixes such as `phar://`. Reported by Sehun Oh of cyberone.kr.\n\n### Impact\nObject injection, possible remote code execution\n\n### Patches\nFixed in 6.0.6 and 5.2.27\n\n### Workarounds\nValidate and sanitise user input before using.\n\n### References\nhttps://nvd.nist.gov/vuln/detail/CVE-2018-19296\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open a private issue in [the PHPMailer project](https://github.com/PHPMailer/PHPMailer)","aliases":["CVE-2018-19296"],"modified":"2024-02-21T05:31:57.978820Z","published":"2020-03-05T22:08:55Z","database_specific":{"cwe_ids":["CWE-1321","CWE-502","CWE-915"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2020-03-05T22:08:10Z","nvd_published_at":"2018-11-16T09:29:00Z"},"references":[{"type":"WEB","url":"https://github.com/PHPMailer/PHPMailer/security/advisories/GHSA-7w4p-72j7-v7c2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-19296"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/phpmailer/phpmailer/CVE-2018-19296.yaml"},{"type":"WEB","url":"https://github.com/PHPMailer/PHPMailer/releases/tag/v5.2.27"},{"type":"WEB","url":"https://github.com/PHPMailer/PHPMailer/releases/tag/v6.0.6"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/12/msg00020.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3B5WDPGUFNPG4NAZ6G4BZX43BKLAVA5B"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KPU66INRFY5BQ3ESVPRUXJR4DXQAFJVT"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3B5WDPGUFNPG4NAZ6G4BZX43BKLAVA5B"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/KPU66INRFY5BQ3ESVPRUXJR4DXQAFJVT"},{"type":"WEB","url":"https://www.debian.org/security/2018/dsa-4351"}],"affected":[{"package":{"name":"phpmailer/phpmailer","ecosystem":"Packagist","purl":"pkg:composer/phpmailer/phpmailer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0"},{"fixed":"5.2.27"}]}],"versions":["v5.2.10","v5.2.11","v5.2.12","v5.2.13","v5.2.14","v5.2.15","v5.2.16","v5.2.17","v5.2.18","v5.2.19","v5.2.2","v5.2.20","v5.2.21","v5.2.22","v5.2.23","v5.2.24","v5.2.25","v5.2.26","v5.2.4","v5.2.5","v5.2.6","v5.2.7","v5.2.8","v5.2.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/03/GHSA-7w4p-72j7-v7c2/GHSA-7w4p-72j7-v7c2.json"}},{"package":{"name":"phpmailer/phpmailer","ecosystem":"Packagist","purl":"pkg:composer/phpmailer/phpmailer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.0.6"}]}],"versions":["v6.0.0","v6.0.1","v6.0.2","v6.0.3","v6.0.4","v6.0.5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/03/GHSA-7w4p-72j7-v7c2/GHSA-7w4p-72j7-v7c2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
