CVE-2024-13094 Scanner

WP Triggers Lite is a widely used WordPress plugin, particularly favored by website administrators and developers for creating dynamic triggers on their sites. This plugin allows users to add customizable triggers based on conditions, useful for enhancing site interactivity and user engagement. The product is often used in conjunction with content management systems to facilitate easy and efficient web management. Many small to medium-sized businesses integrate this plugin to bring more functionality to their WordPress sites. Its architecture supports a variety of themes, making it highly adaptable in the WordPress ecosystem. As a plugin installed in the WordPress platform, it is crucial for maintaining interactive and responsive web pages.

The vulnerability identified in WP Triggers Lite is a Cross-Site Scripting (XSS) flaw, which is a common web security issue. Such vulnerabilities enable attackers to inject malicious scripts into web pages viewed by other users. This particular vulnerability in version 2.5.3 stems from inadequate input sanitization. XSS issues are critical because they can lead to unauthorized actions and access to sensitive user information. The problem arises when HTTP responses are not properly sanitized, resulting in the potential execution of scripts in a user's browser without their knowledge. Addressing XSS vulnerabilities is vital to safeguard against unauthorized script execution and user credential theft.

In technical terms, the vulnerability affects the 'add-trigger' functionality of the WP Triggers Lite plugin, where a specific parameter is not sanitized. This parameter is output on the page, allowing an attacker to craft a special URL with embedded scripts. The scripts can execute within the context of a high-privilege user session if accessed. The primary issues arise on the admin panel page, where JavaScript can be injected and executed. Attackers must leverage social engineering or trick users into clicking malicious URLs for the exploit to work. Proper escaping or sanitization of parameters is notably missing, thus making it vulnerable.

When exploited, this vulnerability allows attackers to execute scripts in the user's web browser, leading to session hijacking or account compromise. High-privilege user sessions are particularly at risk, which can result in administrative access being attained unintentionally by attackers. It may also lead to the injection of further malicious scripts or commands, potentially causing data theft or data integrity issues. If leveraged maliciously, services can be disrupted potentially giving attackers elevated privileges on the system.
