CVE-2023-38519: SQL Injection Vulnerability in MainWP Dashboard – WordPress Manager for Multiple Websites Maintenance

Security researchers have recently discovered an SQL Injection vulnerability, labeled as CVE-2023-38519, in MainWP Dashboard – WordPress Manager for Multiple Websites Maintenance. This security flaw affects versions of the software ranging from n/a to 4.4.3.3. In this post, we will be discussing the details of the vulnerability, including the exploit, original references, and code snippets to better understand its implications and prevent potential cyber attacks.

Exploit Details

The vulnerability is characterized by the improper neutralization of special elements used in an SQL command, which can lead to an SQL Injection. An attacker can exploit this vulnerability by sending a malicious request containing special characters to the affected application, such as %27, which corresponds to a single quote ('), or %23, which corresponds to a number sign (#). If successful, the attacker can potentially modify, read, or delete sensitive database information, as well as execute arbitrary SQL commands.

Code Snippet

The following code snippet demonstrates how the vulnerability can be exploited, using a sample input field and query:

$input_field = "username'; DROP TABLE users; --";
$query = "SELECT * FROM users WHERE username='{$input_field}'";

In this example, the attacker has added a closing single quote to the input field, followed by an SQL command to drop the users table. The "--" at the end of the SQL statement serves as a comment, which effectively makes the rest of the query's content irrelevant.

How to Mitigate the Vulnerability

To protect your WordPress sites from this vulnerability, it is essential to immediately update MainWP Dashboard – WordPress Manager for Multiple Websites Maintenance to the latest version, which contains the necessary security patch. Additionally, you can follow these steps to decrease the risk of an SQL Injection attack:

Use prepared statements and parameterized queries when dealing with user input

Prepared statements and parameterized queries help reduce the risk of SQL Injection attacks by ensuring that user inputs are not treated as executable SQL code.

Perform input validation on all user-submitted data

Ensure that all input received from users is properly validated and sanitized before it is used in any SQL queries.

Limit database permissions

Reduce the potential impact of an SQL injection attack by using the principle of least privilege – restrict the permissions of your database accounts to the bare minimum necessary for their associated tasks.

Implement a web application firewall (WAF)

A WAF can help detect and filter out potentially malicious requests that may contain SQL injection payloads.
