The Easy Forms for Mailchimp is a popular WordPress plugin used to create and manage subscription forms for Mailchimp directly from a WordPress site. This plugin is commonly used by website administrators and digital marketers who aim to simplify the process of capturing leads and integrating them with their Mailchimp accounts. It provides users with a user-friendly interface and various customization options for the subscription forms. The plugin's purpose is to improve the efficiency of email marketing campaigns by ensuring seamless integration with Mailchimp services. Easy Forms for Mailchimp is often employed on small to medium-sized business websites that rely heavily on email marketing strategies.
The vulnerability identified in the Easy Forms for Mailchimp plugin is a Cross-Site Scripting (XSS) flaw that affects versions prior to 6.8.9. This issue arises when the plugin does not adequately sanitize and escape the `sql_error` parameter output on a page while the debug option is enabled. Such vulnerabilities can allow attackers to execute arbitrary JavaScript code in the context of an administrator's browser session. By exploiting this XSS vulnerability, attackers can effectively gain unauthorized access or manipulate web application behaviors.
The technical details of this XSS vulnerability involve improper handling of the `sql_error` parameter by the Easy Forms for Mailchimp plugin. When an administrator enables the debug option, the unsanitized `sql_error` value may be inserted directly into the page’s content, which can be manipulated to include harmful script. An attacker could craft a request that carries a malicious payload, like using SVG tags for script execution, which would be activated upon page load within the admin panel interface. The vulnerability enables arbitrary JavaScript execution, reflecting unsanitized input back to the user's browser without proper validation.
Malicious exploitation of this Cross-Site Scripting vulnerability can lead to severe security risks. Attackers might execute scripts that perform administrative actions, exfiltrate cookies, or redirect administrators to phishing pages. Consequently, they could capture session tokens, enabling unauthorized access to sensitive administrative functionalities within the WordPress website. This vulnerability jeopardizes the integrity and privacy of the website's security management if not promptly patched to restrict such script execution.
