CVE-2022-3766 Scanner

phpMyFAQ is a popular open-source FAQ management software used by organizations and websites to create and manage frequently asked questions. It is typically deployed on PHP-based environments and allows for easy integration with various content management systems. The software is often used by administrators to manage dynamic FAQ sections on websites, enabling users to submit and search for frequently asked questions.

phpMyFAQ versions prior to 3.1.8 have a reflected Cross-Site Scripting (XSS) vulnerability in the search functionality. The application fails to sanitize user input in the search parameter, enabling attackers to inject arbitrary JavaScript code. This vulnerability allows the execution of malicious scripts in the context of another user's browser session.

The XSS vulnerability is triggered when an attacker sends a malicious payload through the search parameter. The payload, once injected into the system, is reflected and executed in the victim's browser. The vulnerable endpoint is the search functionality, and the attack typically involves injecting JavaScript code into the input field. This vulnerability is due to inadequate input validation and escaping of user-supplied data.

If exploited, this vulnerability can allow attackers to execute arbitrary JavaScript code in the context of the victim’s browser. This can lead to data theft, session hijacking, or redirection to malicious websites. Attackers can steal cookies, session tokens, or perform actions on behalf of the user without their consent. The consequences may include further exploitation of the website or web application.
