CVE-2022-48197 Scanner

The Yahoo User Interface library (YUI2) is a set of utilities and controls, for building richly interactive web applications using techniques such as DOM scripting, DHTML, and AJAX. YUI2 was developed by Yahoo and is used by web developers worldwide to enhance the user experience of web pages by providing dynamic content and improved interactivity. It includes components for creating menus, drag-and-drop interfaces, trees, and calendars, among others. Though superseded by newer technologies, YUI2 remains in use in legacy systems and applications. Understanding and addressing vulnerabilities in such libraries is critical due to their widespread use and the potential impact on web application security.

The Cross-Site Scripting (XSS) vulnerability identified in the YUI2 TreeView component through version 2.8.2 allows attackers to inject malicious scripts into web pages. This vulnerability is exploited through crafted URLs that include the XSS payload. When these URLs are accessed, the malicious script executes within the context of the victim's browser, potentially leading to unauthorized access to user session tokens, personal data, and other sensitive information. This vulnerability highlights the importance of sanitizing input and validating data within web applications to prevent such attacks.

This vulnerability specifically affects multiple PHP files within the YUI2 TreeView component, including up.php, sam.php, renderhidden.php, and others. Attackers can exploit this vulnerability by appending a specially crafted query string to the URL, which includes the XSS payload. This query string manipulates the application into executing JavaScript code without proper validation, leading to the reflected XSS attack. The lack of input sanitization for these parameters allows the attacker to inject arbitrary web scripts or HTML, which is executed in the context of the user's session.

Exploitation of this XSS vulnerability in YUI2 could have several consequences, including session hijacking, where attackers gain unauthorized access to the user's session tokens. It could also lead to phishing attacks, where users are tricked into providing sensitive information, and the alteration or theft of information displayed on the web page. Such vulnerabilities compromise the integrity and confidentiality of the user data and can severely damage the reputation and trustworthiness of the affected web applications.
