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.

Weakness

The product does not validate, or incorrectly validates, a certificate.

Affected Software

Name Vendor Start Version End Version
