Description

The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to SQL Injection via the JSON Import in all versions up to, and including, 5.2.7 due to insufficient validation on the user-supplied JSON data. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary SQL queries on the database that can be used to extract information via time-based techniques, drop tables, or modify data.

• 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.
