WordPress Themes Code Injection Scanner

WordPress Themes are widely used by developers and website owners to design and customize websites on WordPress, a popular content management system. They provide the tools and functionalities required to create visually appealing and user-friendly websites. These themes are developed by various companies and individuals aiming to offer diverse features and design elements. Vulnerabilities in themes can affect a large number of users globally because WordPress powers a significant portion of the web. Theme exploitation can lead to compromised websites, data theft, or even full system access.

The Code Injection vulnerability in WordPress Themes identified in certain versions of the epsilon-framework is due to insufficient capability and CSRF nonce checks in AJAX actions. This vulnerability allows attackers to inject malicious code via crafted requests, potentially leading to unauthorized actions on the application. Code Injection is a critical security flaw as it can be exploited for numerous malicious activities, including data exfiltration, service disruption, or unauthorized access. Threat actors leveraging such vulnerabilities can manipulate the website behavior in unintended ways.

Technical details regarding the Code Injection vulnerability in WordPress Themes relate to specific AJAX actions lacking required security checks. The lack of capability and CSRF nonce validation allows attackers to remotely execute arbitrary code on the server. The exploitation vector involves sending specifically crafted POST requests to the admin-ajax.php file. This vulnerable endpoint can be manipulated to perform unauthorized actions, thereby executing injected code within the theme's execution context.

Exploitation of the Code Injection vulnerability can have severe consequences for affected WordPress sites. Malicious actors could gain unauthorized access to sensitive information, corrupt or steal data, and potentially take over the entire site. The site's reputation could be damaged, leading to loss of trust among users and clients. Attackers could also leverage the compromised site for further attacks or malware distribution. Overall, the impact of this vulnerability could be significant, affecting site integrity, availability, and confidentiality.
