Multiple SQL injection vulnerabilities in the replication code in Oracle MySQL possibly before 5.5.29, and MariaDB 5.1.x through 5.1.62, 5.2.x through 5.2.12, 5.3.x through 5.3.7, and 5.5.x through 5.5.25, allow remote authenticated users to execute arbitrary SQL commands via vectors related to the binary log. NOTE: as of 20130116, Oracle has not commented on claims from a downstream vendor that the fix in MySQL 5.5.29 is incomplete.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
