CVE-2023-37979 Scanner Detail

Ninja Forms is a popular WordPress plugin used by website administrators to create and manage forms easily. It provides a user-friendly interface for crafting custom forms for various purposes, such as contact forms, surveys, and feedback submissions. As a plugin for WordPress, it enhances website functionality by allowing for quick integration and customization of forms without the need for extensive coding knowledge. It's widely adopted across different sectors due to its flexibility, extensive features, and integration capabilities with other WordPress plugins and services. This tool is crucial for website owners looking to engage with their audience and collect information in a structured manner.

The reflected Cross-Site Scripting (XSS) vulnerability in Ninja Forms versions prior to 3.6.26 arises from inadequate sanitization and escaping of user inputs. This oversight allows attackers to inject malicious scripts into web pages, which can then be executed in the context of a user's session when the crafted URL is accessed. Such vulnerabilities are particularly concerning as they can be used to target high privilege users, including administrators, leading to potential unauthorized access or manipulation of website content and sensitive data.

This vulnerability is specifically present in the processing of a parameter by Ninja Forms, where it fails to adequately sanitize and escape the input before outputting it back to the page. By crafting a malicious URL that includes an XSS payload targeted at this parameter, an attacker can trigger the vulnerability. When an administrator or high privilege user accesses the manipulated URL, the malicious script is executed, exploiting the vulnerability. This issue was addressed and fixed in Ninja Forms version 3.6.26, highlighting the importance of updating to the latest version to mitigate such security risks.

The exploitation of this XSS vulnerability could lead to several adverse outcomes, including the theft of session cookies, impersonation of privileged users, redirection of users to malicious sites, and the unauthorized modification of website content. For high privilege users, such as administrators, this could result in comprehensive control over the website being compromised, leading to further attacks or the dissemination of malicious content to unsuspecting visitors.
