It is utilized by hundreds of website administrators globally who seek to fulfill event management needs through an easy-to-use calendar system. This plugin integrates seamlessly with WordPress, allowing users to display events with various views, enhancing the user's ability to manage and display events efficiently. The CP Multi View Event Calendar aims to offer flexibility and functionality, enabling users to organize events in monthly or weekly views.

Intended for personal blogs and business websites alike, this plugin is pivotal in event visualization and management for its users.

A SQL Injection (SQLi) vulnerability exists in the WordPress CP Multi View Event Calendar version 1.1.4, which can lead to unauthorized SQL command execution. This type of vulnerability allows attackers to inject malicious SQL code into the database query, which is typically executed through improper validation of inputs. As SQL Injection is a significant vulnerability, it compromises the confidentiality, integrity, and availability of the database. The vulnerability specifically affects the 'id' parameter of the plugin when processed in SQL queries without sufficient sanitization. An attacker could exploit this to execute arbitrary SQL commands, read data from the database, or even modify or delete it. The exposure of the vulnerability lies in its potential to affect the backend operations of the WordPress site.

The vulnerability details reveal that the vulnerable endpoint is associated with the 'id' parameter in the plugin's URL request, specifically under the 'data_management' action. This allows an attacker to perform SQL Injection by appending malicious SQL commands within the 'id' parameter. The SQL payload “1 union all select MD5(123), …” is inserted to demonstrate how arbitrary SQL commands can be injected. This form of attack allows attackers to test the application’s database interactions by checking MD5 value comparisons within the database results. Utilizing SQL union statements, an attacker could leverage this vulnerability to retrieve database table contents by injecting union SQL clauses and learning about the structure and content of the database.

When successfully exploited, the SQL Injection vulnerability in the WordPress CP Multi View Event Calendar can have several detrimental effects. Malicious attackers may gain unauthorized access to sensitive information stored in the database, such as user details and credentials. This breach can result in data theft, unauthorized data manipulation, or even deletion, severely impacting the confidentiality and integrity of data. Additionally, attackers with sufficient skill can establish further attacks, such as web defacement or even site compromise, using the leverage gained through SQL Injection. Therefore, the presence of this vulnerability significantly increases the security risk for any web application that employs the plugin version in question.
