Multiple SQL injection vulnerabilities in the yawpp plugin 1.2 for WordPress allow remote authenticated users with Contributor privileges to execute arbitrary SQL commands via vectors related to (1) admin_functions.php or (2) admin_update.php, as demonstrated by the id parameter in the update action to wp-admin/admin.php.
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.
