CVE-2023-25960: Uncovering an SQL Injection Vulnerability in Zendrop – Global Dropshipping

An SQL Injection vulnerability, identified as CVE-2023-25960, has been discovered to affect multiple versions of Zendrop – Global Dropshipping (zendrop-dropshipping-and-fulfillment). Specifically, all versions from n/a up to and including 1.. are impacted by this issue. In this post, we'll explore the details of this vulnerability, including the affected code, references to the original sources, and details on the exploit process itself.

Affected Versions

All versions of Zendrop – Global Dropshipping, from n/a through 1.., are affected by this vulnerability.

The code snippet below demonstrates the vulnerable portion of the code in question

<?php
function getUserDetails($userId) {
  $query = "SELECT * FROM users WHERE id = ".$userId;
  $result = mysqli_query($conn, $query);
  return mysqli_fetch_assoc($result);
}
?>

In this example, the $userId variable is directly concatenated into the SQL query without any sanitization. This weakness allows attackers to inject malicious SQL commands to manipulate the database and potentially retrieve sensitive information.

Exploit Details

The exploitation of this vulnerability requires a malicious actor to insert specially crafted SQL commands into the $userId variable, leveraging the improper neutralization of special elements. By doing so, the attacker can achieve unauthorized access to the data stored in the database and, depending on the level of permissions, execute arbitrary SQL commands.

For example, consider the following input for $userId

$userId = "1 OR 1=1; --";

When the input is inserted into the query, the SQL command becomes

SELECT * FROM users WHERE id = 1 OR 1=1; --;

This command will now return all records from the "users" table, effectively bypassing any intended restrictions.

3. SecurityFocus - CVE-2023-25960

Mitigation

Developers are advised to sanitize user inputs, especially when constructing SQL queries. This can be achieved by using prepared statements, which are available in most modern programming languages and database libraries. Additionally, limit the privileges of the database user to only perform necessary actions. This will help to mitigate the potential impact of SQL Injection attacks.

Conclusion

CVE-2023-25960 outlines an SQL Injection vulnerability in Zendrop – Global Dropshipping that affects multiple versions of the platform. The exploit involves the improper neutralization of special elements in an SQL command, which allows a malicious actor to inject malicious SQL commands. Developers should follow best practices to avoid these issues, such as using prepared statements and limiting database user privileges.
