The Limit Login Attempts (Spam Protection) plugin for WordPress is designed to protect websites by limiting the number of login attempts from a single IP address, thereby preventing brute force attacks. It's widely used by WordPress site administrators to enhance security and mitigate unauthorized access risks. The plugin is especially useful for websites that face frequent login attempts and is a critical security measure in protecting user data and access. Developers and site administrators deploy this plugin to ensure that their sites remain secure against one of the most common types of cybersecurity threats. Its straightforward implementation and effectiveness make it a popular choice in the WordPress community.

The technical flaw resides in the way the Limit Login Attempts (Spam Protection) plugin processes certain parameters via AJAX actions. Specifically, it fails to properly sanitize and escape user inputs before incorporating them into SQL statements. This oversight allows attackers to inject malicious SQL code through crafted requests to the 'WPLFLA_get_log_data' AJAX action. The vulnerability is triggered when the SQL code is executed by the plugin's backend, leading to potential SQL Injection attacks. Vulnerable endpoints include the 'admin-ajax.php' file, with parameters like 'order[][column]' and 'columns[][data]' being particularly susceptible.

Successful exploitation of this vulnerability could lead to a range of adverse effects, including unauthorized access to sensitive information stored in the website's database, such as user credentials and personal data. Attackers could also modify or delete data, disrupting the website's functionality or defacing it. In severe cases, it could lead to complete control over the affected website, allowing attackers to redirect visitors, deploy malicious content, or leverage the site's resources for further attacks. The breach of data confidentiality, integrity, and availability highlights the critical impact of this vulnerability.
