Exploit Details
A successful SQL injection attack allows an attacker to submit custom SQL commands to a web application's database server, which can result in unauthorized access to sensitive data, such as usernames, passwords, and other critical information. The Avirtum ImageLinks Interactive Image Builder for WordPress contains this flaw due to improper handling and filtering of user-supplied data during the rendering process of images.
To exploit this vulnerability, an attacker may submit a malicious HTTP request containing specially crafted SQL commands to the affected application, like the following example:
https://www.example.com/wordpress/wp-content/plugins/imagelinks-widget/php/request.php?format=metadata&url=https://www.example.com/wordpress/wp-content/uploads/%20UNION%20SELECT%201,username,password,email%20FROM%20wp_users--
The above code snippet constructs a new URL that tricks the plugin into allowing the execution of arbitrary SQL commands. In this case, the sample code retrieves usernames, passwords, and email addresses from the targeted WordPress site's user table.
