CVE-2022-4375: SQL Injection Vulnerability in Mingsoft MCMS

Background

Mingsoft MCMS is an open-source content management system (CMS) developed by Mingsoft Corporation. It is widely used for creating and managing websites, providing features such as content creation, publishing, and user management. The vulnerability identified as CVE-2022-4375 affects Mingsoft MCMS versions up to 5.2.9. This vulnerability allows an attacker to exploit an unknown function in the '/cms/category/list' file, specifically through the manipulation of the 'sqlWhere' argument, leading to SQL injection. The impact of this vulnerability is classified as critical, as it can be exploited remotely and may result in unauthorized access, data leakage, or other malicious activities. The vulnerability has been disclosed publicly, making it crucial for users to upgrade to version 5.2.10 to mitigate the risk.

Vulnerability Detail

The CVE-2022-4375 vulnerability in Mingsoft MCMS arises from a lack of proper input validation and sanitization in the 'sqlWhere' argument of the '/cms/category/list' file. By crafting malicious SQL statements and injecting them into the vulnerable parameter, an attacker can manipulate the underlying SQL query and potentially execute arbitrary SQL commands. This can lead to unauthorized access to the database, data manipulation, or even complete compromise of the affected system. The vulnerability has a CVSS score of 9.8, indicating its severity and the urgency for remediation.

Workaround

As a temporary workaround until the upgrade can be implemented, users can apply input validation and sanitization techniques to the 'sqlWhere' parameter in the '/cms/category/list' file. By implementing proper input validation, including parameterized queries or prepared statements, the risk of SQL injection can be significantly reduced. Here is an example of how to use parameterized queries in Java:

// Assuming 'sqlWhere' is the vulnerable parameter
String sql = "SELECT * FROM categories WHERE sqlWhere = ?";
PreparedStatement statement = connection.prepareStatement(sql);
statement.setString(1, sqlWhere);
ResultSet resultSet = statement.executeQuery();
// Process the results

By using parameterized queries, the user input is treated as data rather than executable code, effectively preventing SQL injection attacks.

Conclusion

The CVE-2022-4375 vulnerability in Mingsoft MCMS poses a critical risk due to its potential for remote SQL injection attacks. It is crucial for users of Mingsoft MCMS versions up to 5.2.9 to upgrade to version 5.2.10 or later to mitigate this vulnerability. Implementing proper input validation and sanitization techniques, such as parameterized queries, is also recommended.
