CVE-2024-3032 Scanner

The WordPress Themify Builder plugin is a widely used drag-and-drop builder for WordPress websites, allowing users to create custom layouts and designs without needing coding expertise. It is primarily used by WordPress site owners and developers to enhance the visual appeal and functionality of their websites. The plugin provides a user-friendly interface for building responsive designs, making it a popular choice for businesses and personal blogs alike. Its applications range from simple blog setups to complex e-commerce platforms, supporting a wide range of customizations. With its extensive template library and add-on support, users can design visually striking and highly functional sites at scale. However, due to its complexity and widespread use, the plugin is susceptible to various security vulnerabilities.

An open redirect vulnerability exists within the WordPress Themify Builder plugin versions prior to 7.5.8. This type of vulnerability occurs when a web application allows users to pass information to it through parameters, and then redirects users to the provided value without proper validation. Open redirects can be exploited by attackers to redirect users to malicious websites or phishing pages, creating an avenue for potential attacks. Such vulnerabilities can arise from improper handling of URL redirects, often due to simplistic parameter validation or inadequate filtering of user inputs. Understanding and mitigating this vulnerability is crucial for maintaining the security integrity of websites using the plugin. This particular vulnerability is marked by its potential to mislead users and facilitate social engineering attacks.

The vulnerability resides in the tb_redirect_fail parameter, which is not validated before redirecting users. This technical flaw allows attackers to manipulate URL redirection by sending crafted requests to WordPress websites using the plugin. When malformed inputs are submitted, the plugin redirects users to external URLs set by the attacker. This redirection bypass occurs due to the absence of validations that ensure the URLs adhere to intended site paths or validated domains. Attackers often exploit such vulnerabilities by directing unsuspecting users to phishing pages or downloading malware. The vulnerable parameter tb_redirect_fail can lead to significant security breaches if not addressed appropriately.

If exploited, the open redirect vulnerability can pose several potential risks to users and site owners alike. Users might unknowingly be redirected to phishing sites, thereby compromising sensitive information such as login credentials, personal data, or financial information. Unchecked redirections can also diminish user trust in the website's legitimacy, potentially affecting visitor loyalty and engagement. Additionally, malicious redirects may facilitate injection or inclusion of harmful scripts that compromise site stability or data integrity. Exploitation may further lead to blacklisting by search engines or security watchdog entities, due to redirection pathways linked to malicious activities.
