CVE-2024-0699 in AI Engine Plugin
Summary
by MITRE • 02/06/2024
The AI Engine: Chatbots, Generators, Assistants, GPT 4 and more! plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'add_image_from_url' function in all versions up to, and including, 2.1.4. This makes it possible for authenticated attackers, with Editor access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE-2024-29100 is likely a duplicate of this issue.

The vulnerability identified as CVE-2024-0699 affects the AI Engine WordPress plugin, specifically targeting versions up to and including 2.1.4. This plugin provides chatbot and AI assistant functionality for WordPress sites, making it a potentially attractive target for attackers seeking to compromise WordPress installations. The vulnerability stems from inadequate input validation within the add_image_from_url function, which fails to properly verify the file types being uploaded. This flaw creates a critical security gap that allows authenticated users with Editor privileges or higher to bypass normal file upload restrictions and execute arbitrary file uploads on the affected server. The issue represents a classic example of insecure file upload vulnerabilities that can lead to complete system compromise when combined with other attack vectors.
The technical implementation of this vulnerability involves the absence of proper file type validation in the plugin's file handling mechanism. When users with Editor access or higher attempt to upload files through the add_image_from_url function, the system does not properly verify the MIME types or file extensions of the uploaded content. This validation gap allows attackers to upload files with potentially malicious extensions such as php, aspx, or other server-side script files that could execute code on the web server. The vulnerability falls under CWE-434 which specifically addresses insecure file upload handling, where the system fails to validate file types and content, leading to potential code execution. The flaw is particularly dangerous because it requires only Editor-level privileges, which are commonly granted to content creators and administrators within WordPress environments, making exploitation relatively accessible.
The operational impact of this vulnerability extends beyond simple file uploads, as it opens the door to remote code execution capabilities that can result in complete system compromise. An attacker who successfully exploits this vulnerability can upload malicious files that execute arbitrary code on the target server, potentially allowing them to gain full control over the WordPress installation and underlying server infrastructure. This threat model aligns with ATT&CK technique T1505.003 which covers server-side injection via file upload vulnerabilities. The compromise can lead to data theft, service disruption, and the establishment of persistent backdoors within the affected WordPress environment. Given that many WordPress sites host sensitive data and are critical to business operations, the potential damage from such an exploit is significant, especially when considering that the vulnerability affects a widely used plugin that may be installed on numerous websites across different organizations.
The security implications of CVE-2024-0699 are compounded by the fact that it affects a plugin that is likely installed on numerous WordPress sites, potentially creating a widespread attack surface. The vulnerability's requirement for only Editor-level access makes it particularly concerning as it can be exploited by users who have legitimate content management responsibilities but may be compromised or malicious. The plugin's functionality as a chatbot and AI assistant system means that it likely has access to various server resources and could potentially be used to escalate privileges or establish persistent access. Organizations should immediately implement mitigations including plugin updates, file type validation enforcement, and access control restrictions to prevent exploitation. The vulnerability also highlights the importance of proper input validation and the need for security testing of third-party WordPress plugins to prevent similar issues in the future.
