DataEase is a popular open-source data visualization analysis tool used by organizations and individuals worldwide to analyze, visualize, and present their data in a more comprehensible manner. In this post, we will discuss a significant security vulnerability (CVE-2023-37258) found in versions prior to 1.18.9, which allows attackers to perform SQL Injection attacks and bypass blacklists. We will also provide code snippets to showcase the exploitation and provide links to original references and details on how to fix the issue.

The Vulnerability: CVE-2023-37258 - SQL Injection
In versions prior to 1.18.9, DataEase was found to have a SQL injection vulnerability that could allow attackers to execute arbitrary SQL queries to manipulate the application's database, potentially exposing, modifying, or even destroying sensitive data. This issue stems from the improper handling of user input and inadequate sanitization of SQL queries.

To exploit this vulnerability, an attacker can provide a crafted input that includes SQL commands to manipulate the database queries. The following is an example code snippet that demonstrates the injection point and vulnerable code:

// Vulnerable Code Snippet
String sqlQuery = "SELECT * FROM users WHERE username = '" + username + "' AND password = '" + password + "'";

try {
    Statement stmt = connection.createStatement();
    ResultSet rs = stmt.executeQuery(sqlQuery);

    // Process the result set
}
catch (SQLException e) {
    // Handle SQL exception
}

In this example, an attacker can insert an always-true condition (e.g., ' OR '1'='1) into the input fields, which can lead to bypassing security measures like blacklists and potentially accessing unauthorized data.
