Backdrop CMS is a content management system aimed at providing a cost-effective and easy-to-use online platform for individuals, businesses, and non-profits. It allows users to create and manage their websites with ease, offering various features such as customizable layouts, extensive modules, and user-friendly interfaces. Developed and maintained by a community of volunteers, Backdrop CMS is designed for those seeking an alternative to more complex CMS platforms. Its architecture is particularly suited for small to medium-sized projects, providing a robust framework for web development and content management. Version 1.23.0 of Backdrop CMS, while offering new functionalities and improvements, unfortunately, includes a vulnerability that could compromise the security of websites.

The Cross-Site Scripting (XSS) vulnerability found in Backdrop CMS version 1.23.0 pertains to the storage and execution of malicious scripts through the Post content. This type of vulnerability allows attackers to inject client-side scripts into web pages viewed by other users. As a result, it can be used to bypass access controls, manipulate website content, or steal sensitive information from unsuspecting users. The stored XSS vulnerability is particularly concerning because it does not require immediate interaction from the victim to be exploited.

The stored XSS vulnerability in Backdrop CMS 1.23.0 allows attackers to submit malicious JavaScript code via the Post content section. This code is improperly sanitized by the CMS before being stored, making it possible for the script to execute in the browser of any user viewing the content. Specifically, the vulnerability is exploitable through the addition of a specially crafted `` tag with a JavaScript event handler. The submission process involves authenticated access to the CMS, indicating that the vulnerability can be exploited by users with the capability to create or edit Post content.

Exploitation of this XSS vulnerability could lead to several adverse effects, including theft of session cookies, personal information, or other sensitive data. Attackers could also leverage this vulnerability to perform actions on behalf of users or administrators, manipulate or deface web content, and potentially gain unauthorized access to the CMS. Such incidents could undermine user trust, compromise data integrity, and expose the site to further attacks.
