SERVER-MYSQL -- Snort has detected traffic exploiting vulnerabilities in MySQL servers.
SERVER-MYSQL MySQL/MariaDB client authentication bypass attempt
sql/password.c in Oracle MySQL 5.1.x before 5.1.63, 5.5.x before 5.5.24, and 5.6.x before 5.6.6, and MariaDB 5.1.x before 5.1.62, 5.2.x before 5.2.12, 5.3.x before 5.3.6, and 5.5.x before 5.5.23, when running in certain environments with certain implementations of the memcmp function, allows remote attackers to bypass authentication by repeatedly authenticating with the same incorrect password, which eventually causes a token comparison to succeed due to an improperly-checked return value. Impact: CVSS base score 5.1 CVSS impact score 6.4 CVSS exploitability score 4.9 confidentialityImpact PARTIAL integrityImpact PARTIAL availabilityImpact PARTIAL Details: Ease of Attack:
An authentication bypass is triggered in the MySQL/MariaDB client when a flood of authentication requests are sent.
