A recent security vulnerability, registered as CVE-2024-25902, has been discovered in the miniorange Malware Scanner plugin for WordPress. This SQL Injection vulnerability allows attackers to compromise the integrity and confidentiality of users' data in WordPress websites. This issue affects miniorange Malware Scanner versions from its initial release to version 4.7.2. Immediate action is required to secure websites using this plugin.

Background

SQL Injection is a critical vulnerability that exploits improper neutralization of special elements in SQL commands. It occurs when an attacker can insert malicious SQL queries through user inputs, leading to unauthorized access to the sensitive data in the database. Attackers can also modify or delete data and execute administrative operations on the database.

In this article, we'll be examining the details of the vulnerability, a sample code snippet exposing the vulnerability, and how to exploit it. We will also provide links to original references, so you can take appropriate actions to enhance your website's security.

Vulnerability Details

The vulnerability exists due to insufficient input validation in the "search_for_pattern" function of the miniorange Malware Scanner. This function is responsible for searching and identifying potential malware signatures in various files within the WordPress installation. The input parameter "search" is not adequately sanitized, allowing an attacker to inject malicious SQL queries through this parameter.

Exploit

Exploiting this vulnerability involves sending a crafted search request to the WordPress server running the affected miniorange Malware Scanner version. When a user submits a search request containing malicious input, the injected SQL query will cause havoc in the database, compromising data confidentiality and integrity.

The following is an example code snippet illustrating the SQL Injection vulnerability

function search_for_pattern($search, $file_path) {
    global $wpdb;
    // ... other code ...
    $query = "SELECT * FROM $table WHERE pattern = '" . $search . "';";
    $results = $wpdb->get_results($query);
    // ... other code ...
}

In this code snippet, the $search parameter is directly included in the $query variable without proper input sanitization. As a result, an attacker could insert an SQL query such as ' OR '1'='1 as a search input, resulting in the following malicious query:

"SELECT * FROM $table WHERE pattern = '' OR '1'='1';"

This query would return all the records in the $table, giving the attacker unauthorized access to sensitive data.

Solution

To address this vulnerability, it is crucial to update your miniorange Malware Scanner plugin to the latest version, which contains fixes for the issue. You can follow these steps to update your plugin:

Alternatively, you can download the latest version of miniorange Malware Scanner from the official WordPress Plugin Repository:
