Vulnerability Overview

The WP Simple Booking Calendar WordPress plugin before 2.0.7 did not escape, validate or sanitise the orderby parameter in its Search Calendars action, before using it in a SQL statement, leading to an authenticated SQL injection issue

Technical Analysis

REMEDIATION: Update to version 2.0.7, or a newer patched version --- IDENTIFIER: CWE-89 (Improper 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.
