Description

The WP Directory Kit WordPress plugin before 1.5.5 does not sanitize and escape a parameter before using it in a SQL statement through one of its authenticated AJAX actions, which lacks authorization and nonce checks, allowing any authenticated user such as a Subscriber to perform SQL injection attacks.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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.
