CVE-2024-7354 Scanner

Ninja Forms is a popular WordPress plugin used by website administrators to seamlessly create forms for their site. It is commonly used for contact, subscription, and feedback forms, among others. Webmasters leverage Ninja Forms for its user-friendly interface and customizable templates. The plugin is extensively used by WordPress sites looking for easy integration and functionality customization. However, maintaining up-to-date versions is crucial to ensure form and data security. Failure to update can lead to security vulnerabilities, potentially exposing sensitive information.

Cross-Site Scripting (XSS) is a frequent security vulnerability found in web applications where the attacker injects scripts into content returned to users. This type of attack can lead to the execution of arbitrary scripts in the context of the user session in many different environments, from emails to browser exploits. Reflection of the malicious script due to inadequate input sanitization allows hackers to execute their payloads. Successful exploitation can result in unauthorized actions being performed on behalf of the user. The vulnerability can compromise trust as well as sensitive information.

The vulnerability details of this specific issue involve an unescaped URL in the Ninja Forms plugin versions before 3.8. This flaw allows an attacker to input malicious scripts that reflect on a user’s browser, particularly affecting high-privilege users like administrators. This results from inadequate sanitization of URL parameters that are echoed in the output HTML. Attackers can exploit this by tricking users into clicking a crafted URL, executing the script and potentially giving attackers access to privileged information. Remedying this requires securing URL inputs and outputs to prevent harmful scripts from running.

The exploitation of Cross-Site Scripting (XSS) vulnerabilities can have severe impacts. Attackers may obtain unauthorized access to user sessions, enabling them to act on behalf of authenticated users. This can lead to stolen credentials, unauthorized data changes, or even complete system compromise. Admin-level users might install malicious plugins, modify site content, or execute arbitrary server-side commands. A successful exploit not only compromises the target application but can also affect end-users, diminishing trust and credibility. It's crucial to patch vulnerabilities promptly to mitigate these risks.
