CVE-2015-3152

MEDIUM

Oracle MySQL <5.7.3 & MariaDB <5.5.44 - Info Disclosure

Title source: llm

Description

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.
