CVE-2024-4620 Scanner

ArForms is a popular WordPress form builder plugin used by web administrators and developers to create and manage forms on WordPress websites. The plugin has been developed by reputeinfosystems and is utilized by a wide range of users, from small business owners to large organizations, to enhance the functionality of their websites through custom form integration. The primary purpose of ArForms is to provide an intuitive, user-friendly interface for creating forms, offering features like form analytics and multiple field types to cater to varied user needs. By facilitating easy form creation, the plugin plays a crucial role in collecting data, improving user engagement, and enhancing user interaction on WordPress sites. Utilized across different domains, ArForms is an essential tool for marketers, customer service teams, and technical staff alike, helping them to create forms without requiring extensive coding skills.

The Remote Code Execution (RCE) vulnerability identified in ArForms allows unauthorized users to execute arbitrary code on the server where the plugin is installed. This serious security flaw, found in plugin versions before 6.6, could be exploited by attackers to gain control over vulnerable WordPress websites. An RCE vulnerability such as this one is critical because it can be executed remotely, without requiring prior access or authentication, leading to potential full control over a web application. This exploit is particularly dangerous for users of the ArForms plugin, as it can lead to unauthorized access and compromise of sensitive data managed through the forms. It is a part of a broader class of security issues involving the improper handling of file uploads, which are common in web applications with customizable input features like this plugin.

Technical details of this vulnerability reveal that the problem stems from how the plugin handles uploaded files, allowing PHP code to be executed through a file upload input. Attackers can manipulate these file uploads to include malicious PHP code, which is subsequently executed when the file is imported or processed by the server. The exploit involves several HTTP requests intended to first modify the upload and then execute PHP code uploaded via manipulated form input. Successful exploitation of this vulnerability requires constructing specific payloads that trick the server into executing injected PHP scripts, enabling the attacker to perform potentially harmful actions like altering content, stealing data, or even further penetrating the host server.

Possible effects of exploiting the RCE vulnerability in ArForms include loss of control over the WordPress site, unauthorized data access, data leakage, and possibly the installation of backdoors for persistent access by attackers. Websites compromised through this vulnerability may also experience degraded performance or be used as part of broader attack campaigns. For businesses and site owners, the results of such exploitation can include reputational damage, financial losses due to site downtime or data breaches, and legal ramifications if sensitive user information is exposed. In severe cases, an attacker with RCE capabilities could leverage this access to further compromise the underlying server infrastructure, leading to potentially catastrophic impacts on the organization's IT environment.
