A CMS contains a SQL injection vulnerability in admin/db_data.php at line 509 that allows authenticated administrators to inject arbitrary SQL into a SHOW COLUMNS FROM statement by supplying unsanitized input through the table_name GET or POST parameter. Attackers can perform table traversal, time-based blind, boolean-based blind, and error-based injection techniques to enumerate full database schema, access system tables such as information_schema, and chain the disclosure with secondary injection points to extract credential data.
