CVE-2012-2122: 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 MariaD...

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.

Security readout for executives and security teams

This flaw can let an attacker log in to vulnerable MySQL or MariaDB servers with the wrong password in specific operating environments. For exposed databases, that could mean unauthorized access to business data. The issue is old, version-specific, and environment-dependent, but public exploit references exist, so any remaining legacy exposure should be treated seriously. Most exposure is likely legacy MySQL or MariaDB still running affected 5.1, 5.2, 5.3, 5.5, or early 5.6 versions. Risk is highest where database authentication is reachable from untrusted networks and the host environment uses an affected memcmp behavior. Prioritize remediation where affected database versions are internet-facing, partner-facing, or reachable from broad internal networks. Legacy internal-only systems still warrant cleanup, but urgency depends on reachability and data sensitivity. Mitigation focus: Upgrade MySQL to 5.1.63, 5.5.24, 5.6.6, or later.; Upgrade MariaDB to 5.1.62, 5.2.12, 5.3.6, 5.5.23, or later.; Restrict database access to trusted networks and application hosts..
