Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack. Oracle MySQL en versiones anteriores a 5.7.3, Oracle MySQL Connector/C (también conocido como libmysqlclient) en versiones anteriores a 6.1.3 y MariaDB en versiones anteriores a 5.5.44 utiliza la opción --ssl significa que SSL es opcional, lo que permite a atacantes man-in-the-middle suplantar servidores a través de un ataque de degradación de texto plano, también conocida como un ataque "BACKRONYM". It was found that the MySQL client library permitted but did not require a client to use SSL/TLS when establishing a secure connection to a MySQL server using the "--ssl" option. A man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server. • http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161436.html http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161625.html http://mysqlblog.fivefarmers.com/2014/04/02/redefining-ssl-option http://mysqlblog.fivefarmers.com/2015/04/29/ssltls-in-5-6-and-5-5-ocert-advisory http://packetstormsecurity.com/files/131688/MySQL-SSL-TLS-Downgrade.html http://rhn.redhat.com/errata/RHSA-2015-1646.html http://rhn.redhat.com/errata/RHSA-2015-1647.html http://rhn& • CWE-295: Improper Certificate Validation •
