SQL injection vulnerability in the Photo Gallery plugin before 1.2.11 for WordPress allows remote authenticated users to execute arbitrary SQL commands via the asc_or_desc parameter in a create gallery request in the galleries_bwg page to wp-admin/admin.php.
Improper Neutralization of Special Elements used in an SQL Command 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.
