How the Exploit Works
The vulnerability resides in the improper neutralization of special elements used in an SQL command within the GG Bought Together for WooCommerce plugin. This allows an attacker to insert malicious SQL statements into an entry field for execution, potentially leading to unauthorized viewing, modification, or deletion of data within the database. This type of attack, known as SQL Injection, is a common and potent threat to web applications that do not properly sanitize user input.
Conceptual Example Code
A potential exploit might look something like this:
POST /add-to-cart HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
product_id=1' UNION SELECT user_pass FROM wp_users WHERE ID = 1 --In the above example, the malicious payload ‘1’ UNION SELECT user_pass FROM wp_users WHERE ID = 1 — is injected via the product_id parameter. This could potentially return the hashed password of the first user in the wp_users table, typically the site admin, leading to unauthorized access.
Recommendations for Mitigation
The best course of action to mitigate this vulnerability is to apply the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. These tools can help identify and block SQL Injection attempts, reducing the risk of exploitation.
It’s also good practice to ensure that all software, not just the GG Bought Together for WooCommerce plugin, is kept up-to-date with the latest patches and updates to reduce the risk of vulnerabilities.
