LeagueManager SQL Injection Scanner

LeagueManager is a plugin designed to seamlessly integrate with WordPress, offering features for managing and displaying sports league data on websites. Utilized predominantly by sports enthusiasts, administrators of sports websites, and clubs, this plugin simplifies the organization and presentation of league standings, schedules, and statistics. It supports multiple sports types and customizable league structures, making it versatile for a wide range of sports. Moreover, with its ease of use and powerful capabilities, LeagueManager is popular among sports clubs that wish to engage their audience with dynamic league data.

SQL Injection is a critical vulnerability that occurs when user-supplied data is not correctly sanitised before being incorporated into an SQL query. It enables attackers to manipulate the queries executed by the database, potentially leading to unauthorized data access or manipulation. In LeagueManager, this vulnerability is presented in the form of unsanitized input in AJAX actions accessible to unauthenticated users. Exploiting this flaw can allow an attacker to execute arbitrary SQL commands on the database. As a result, sensitive data could be exposed, altered, or deleted, threatening the integrity and confidentiality of the database contents. Protection against SQL Injection is crucial for ensuring the security and reliability of applications that interact with databases.

The SQL Injection vulnerability in LeagueManager is due to improper validation of a parameter used in an AJAX action. The specific endpoint does not escape user inputs before utilizing them in SQL statements, allowing injection through crafted requests. Attackers exploit such vulnerabilities by embedding SQL code within data inputs, bypassing normal authentication mechanisms. This vulnerability can be leveraged using time-based SQL Injection techniques to determine blind injection points, as referenced in the template's HTTP request structure. In the example provided, the injected SQL sleep function delays the response, identifying successful exploitation via response time measurement. Close scrutiny of all input-handling capabilities of the plugin is necessary for identifying such security lapses.

Exploiting SQL Injection can lead to dire consequences, including the compromise of sensitive information such as usernames, passwords, or personal data. Attackers could potentially gain administrative access to the system, allowing them to alter or delete data and even take control of the web server. The manipulation of database contents can disrupt service operations, resulting in financial and reputational repercussions for the affected party. In addition, exploiting such a vulnerability might enable an attacker to pivot and exploit other components of the web application, escalating the attack beyond the initial entry point. Thus, preventing exploitation is essential for maintaining the service's integrity and protecting user data.
