The Slider & Popup Builder by Depicter is a popular WordPress plugin used to create responsive sliders and popups with ease. It is widely used by web developers and website owners to enhance the interactivity and visual appeal of their sites. The tool allows users to build engaging and dynamic web content without needing to code extensively. The plugin is often utilized in marketing campaigns to capture user attention or gather leads through forms and interactive sliders. With its user-friendly interface, the plugin is accessible to both novice and experienced users, making it a favored choice in the WordPress ecosystem.
The SQL Injection vulnerability in the Slider & Popup Builder by Depicter plugin allows attackers to manipulate and execute arbitrary SQL queries on the database. This particular vulnerability arises due to improper handling and escaping of user-supplied data, specifically via the 's' parameter. Malicious actors can exploit this flaw by appending rogue SQL commands, potentially leading to unauthorized database access and data leakage. SQL Injection is a critical vulnerability as it can compromise data integrity and confidentiality if leveraged by attackers. Given the widespread use of this plugin, stakeholder awareness and timely updates are crucial to mitigating potential risks.
This SQL Injection vulnerability is exploited by sending specially crafted requests to the WordPress admin-ajax.php file, using the 's' parameter in the plugin. The crafted SQL payload can include UNION statements and database function calls, exposing database structures and contents. The lack of input validation and sanitization allows attackers to append these SQL snippets into existing queries. The vulnerable code resides within the LeadsAjaxController and related database handling components. Penetration of this vulnerability can reveal sensitive information stored in the WordPress database, a lucrative target for attackers seeking confidential information.
Exploitation of this SQL Injection vulnerability can lead to severe consequences, including unauthorized data retrieval, alteration, or deletion of sensitive information from the database. Malicious exploitation could disrupt service operations, result in information theft, and damage data integrity, affecting user trust and the business's reputation. Additionally, compromised databases could be manipulated to deploy further attacks, spreading the security breach beyond the initial compromise. Mitigation involves securing database interactions by properly validating and escaping user input to prevent tampering or injection.
