Background

RuoYi is an open-source package available on Maven that provides a comprehensive framework for building enterprise-level applications. It offers various features and functionalities to facilitate the development process. However, RuoYi versions up to v4.6 have been found to be vulnerable to a SQL injection attack. This vulnerability can be exploited through the '/system/dept/edit' endpoint.

Vulnerability Detail

The SQL injection vulnerability in RuoYi allows an attacker to manipulate SQL queries by injecting malicious input. By exploiting this vulnerability, an attacker can execute arbitrary SQL commands, potentially gaining unauthorized access to the database or modifying its contents. This can lead to data breaches, data manipulation, or even complete system compromise. The vulnerability has been assigned a severity rating of HIGH.

Workaround

If upgrading to a newer version is not immediately feasible, a temporary workaround can be implemented by validating and sanitizing user input before using it in SQL queries. This can be achieved by using parameterized queries or prepared statements, which ensure that user input is treated as data rather than executable code. Here is an example of how to use prepared statements in Java:

// Assuming 'conn' is the database connection
String sql = "SELECT * FROM users WHERE username = ? AND password = ?";
PreparedStatement statement = conn.prepareStatement(sql);
statement.setString(1, username);
statement.setString(2, password);
ResultSet resultSet = statement.executeQuery();
// Process the result set

By using prepared statements, the input is automatically escaped and treated as data, mitigating the risk of SQL injection.

Conclusion

The SQL injection vulnerability in RuoYi versions up to v4.6 poses a significant risk to the security and integrity of the application and its underlying database. It is crucial to promptly upgrade to a newer version that addresses this vulnerability. If immediate upgrading is not feasible, implementing proper input validation and sanitization techniques can serve as a temporary workaround.
