WordPress AIT CSV Import Export Remote Code Execution Scanner

The AIT CSV Import Export plugin for WordPress is typically used by website administrators and developers who need to manage data import and export processes efficiently. It is designed to streamline the interchange of data between the WordPress site and external systems, such as CSV files, making it useful for bulk content management. E-commerce sites, bloggers, and businesses that frequently update their content or product databases find it particularly helpful. By enabling automation of data transfer, it reduces manual effort, thereby enhancing productivity. The plugin is popular among those seeking to simplify data handling without extensive technical knowledge. Overall, the AIT CSV Import Export plugin plays a significant role in maintaining content up-to-date and facilitates data integration solutions.

The Remote Code Execution vulnerability in the AIT CSV Import Export plugin can result in unauthorized code execution on a vulnerable WordPress site. When exploited, attackers can upload and execute arbitrary PHP scripts without authentication, leading to potential system compromise. As it does not require authentication, this vulnerability poses a high risk due to ease of exploitation. Successful execution of malicious code can facilitate further unauthorized actions, compromising data integrity and confidentiality. Attackers could leverage this vulnerability for varied malicious activities such as data theft, website defacement, or even hosting phishing sites. Such security flaws emphasize the need for robust validation on upload functions to prevent unauthorized code execution.

This vulnerability is present in the plugin's upload-handler.php file, where an unauthenticated attacker can upload a PHP file by sending a crafted multipart/form-data POST request. The vulnerable endpoint allows files to be uploaded without proper authentication or content validation. There is no check to ensure that the uploaded file is of an allowed type, which leads to this security flaw. The lack of validation makes this endpoint susceptible to malicious file uploads. Once uploaded, these files may be executed remotely, thereby allowing the attacker arbitrary code execution. Monitoring and securing these endpoints against improper upload and execution of files is critical for protecting against such vulnerabilities.

When exploited, malicious actors could gain control over the affected WordPress site, perform unauthorized actions, and manipulate website content. They might execute scripts that can exfiltrate sensitive data or initiate further attacks, such as installing backdoors or launching lateral movements within the network. Consequently, the integrity of data is at risk, potentially leading to data breaches and violation of sensitive information. The effects might even extend to the exposure or theft of user credentials and personal information. Furthermore, the presence of such vulnerabilities can lead to reputational damage for the organization operating the compromised website. It is crucial to apply fixes and safeguard systems promptly to prevent these adverse effects.
