Description

The WP Directory Kit WordPress plugin before 1.5.7 does not sanitise and escape a parameter before using it in a SQL statement, allowing administrators to perform SQL injection attacks. On a multisite installation this lets an administrator of a single site read data belonging to the entire network, which they are not otherwise able to reach.

• 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.
