CVE-2023-4666 Scanner

Form Maker by 10Web is a popular WordPress plugin primarily utilized by web developers and site administrators for creating responsive forms with simple drag-and-drop functionality. It is widely used to enhance user interaction on websites through various forms, surveys, and questionnaires. The plugin's ease of use and customization features make it an attractive choice for non-technical users looking to implement dynamic forms seamlessly. This software is commonly employed by businesses, educational institutions, and individual bloggers alike, aiming to collect user data effectively. The plugin integrates efficiently with WordPress sites making it a practical tool for managing user interactions. As it handles user data, maintaining its security is crucial to prevent unauthorized data manipulation.

The Unauthenticated Arbitrary File Upload vulnerability allows attackers to upload potentially malicious files to a server without any authentication, exploiting the lack of safeguards in place. This vulnerability, by bypassing authentication mechanisms, can result in unauthorized actions on the server, leading to remote code execution (RCE). It exploits the plugin's failure to validate incoming user inputs properly, providing a gateway for the attacker. This type of vulnerability can cause immense disruption by allowing the attacker to alter, access, and manipulate files within the server. The form maker plugin versions prior to 1.15.20 are susceptible, requiring immediate attention to mitigate risks.

Technically, this vulnerability occurs due to the plugin's inadequate validation of signatory fields when creating files from user inputs. The absence of proper authentication checks leads to unauthorized endpoints remaining exposed, allowing arbitrary file uploads. When inputs from unauthorized users are processed, it enables unrestricted access to create files on the server. Such vulnerabilities are typically leveraged by attackers to execute harmful scripts or gain privileged system access. The endpoint responsible for processing these requests lacks the mechanisms to verify if the individual uploading files has proper authorization, making it a significant security flaw.

Unauthenticated Arbitrary File Upload vulnerabilities can have severe ramifications when exploited. They could lead to the introduction of malicious software or ransomware into the server environment. Attackers can also explore these vulnerabilities to escalate privileges, gain unrestricted access to sensitive data, and disrupt services. This can culminate in a complete system compromise, deceiving users and potentially leading to data theft and loss. Furthermore, successful exploitation can lead to reputational damage, legal ramifications, and loss of customer trust, especially if personal data becomes inaccessible or corrupted.
