| Title | Moodle の Amazon S3 ライブラリの repository/s3/S3.php における SSL サーバになりすまされる脆弱性 |
|---|---|
| Summary | Moodle の Amazon S3 ライブラリの repository/s3/S3.php は、サーバのホスト名が X.509 証明書のサブジェクトの Common Name (CN) または subjectAltName フィールドのドメイン名と一致することを検証しないため、SSL サーバになりすまされる脆弱性が存在します。 |
| Possible impacts | 中間者攻撃 (man-in-the-middle attack) により、任意の有効な証明書を介して、SSL サーバになりすまされる可能性があります。 |
| Solution | ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。 |

| Summary | repository/s3/S3.php in the Amazon S3 library in Moodle through 2.2.11, 2.3.x before 2.3.9, 2.4.x before 2.4.6, and 2.5.x before 2.5.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, related to an incorrect CURLOPT_SSL_VERIFYHOST value. |
