CVE-2023-1890 Scanner

Tablesome is a dynamic table plugin for WordPress that allows users to create, manage, and display responsive tables on their websites. Developed by Pauple, it's designed for website owners, bloggers, and developers seeking a straightforward way to present data in table format without needing to code. Tablesome supports various data types, including text, images, links, and buttons, making it versatile for different use cases such as product listings, data comparisons, or contact directories. Its user-friendly interface and customization options enable users to tailor tables to their specific design and functionality requirements. As a widely used plugin, maintaining its security is crucial to protect websites and user data from potential threats.

The XSS vulnerability in Tablesome versions prior to 1.0.9 is caused by insufficient sanitization of the 'tab' parameter inputs and inadequate escaping of output. This flaw allows attackers to inject and execute arbitrary JavaScript code on the pages viewed by other users, compromising the security of user sessions and potentially leading to unauthorized access or manipulation of sensitive data. Such vulnerabilities pose significant risks to website integrity and user privacy, highlighting the importance of input validation and output encoding in web applications.

This specific XSS vulnerability exploits the plugin's handling of URL parameters, particularly the 'tab' parameter. An attacker crafts a malicious URL containing a JavaScript payload that, when processed by Tablesome on a vulnerable WordPress site, executes the script within the user's browser. This exploitation technique reflects the script back to the user, effectively bypassing the plugin's security measures. The affected functionality is likely part of the plugin's administrative interface or settings page, where the 'tab' parameter is used to navigate between different sections or features.

The exploitation of this XSS vulnerability can lead to various adverse outcomes, including session hijacking, where attackers take control of a user's session to perform unauthorized actions; theft of sensitive information such as cookies or authentication tokens; and website defacement, altering the appearance or content of the site. Such incidents can undermine user trust, damage the site's reputation, and potentially lead to financial or data losses.
