CVE-2019-12935 Scanner

Shopware is a widely used e-commerce software that provides features for managing online stores, including products, orders, and customer data. It offers a user-friendly interface for merchants to customize and manage their online presence efficiently. Businesses of all sizes, from small retailers to large enterprises, utilize Shopware to enhance their digital sales operations. As an enterprise-grade solution, it is equipped with tools for marketing, merchandising, and search engine optimization. The platform is modular, allowing users to extend its functionality with plugins and customizations. Shopware is favored for its scalability, flexibility, and robust community support.

The Cross-Site Scripting (XSS) vulnerability in Shopware allows attackers to inject malicious scripts into web pages viewed by other users. This type of vulnerability typically appears when input fields do not properly sanitize user inputs, leading to unauthorized script execution in a user's browser. In the case of Shopware, the vulnerability exists due to unsanitized query string parameters in specific URI endpoints. This vulnerability can lead to a range of security issues, including the hijacking of user sessions and the defacement of web pages. XSS vulnerabilities are a common vector for dispersing malware and gaining unauthorized access to sensitive user information.

The Shopware XSS vulnerability is exploited by crafting specific URLs that include malicious scripts within unsanitized query parameters. These scripts are then executed when a targeted user attempts to visit the crafted URL. The vulnerable endpoints identified in Shopware include back-end login interfaces that mistakenly accept unfiltered script input. This includes a scenario where an attacker sends a crafted URL containing a script embedded in the query string, which gets executed within the victim's browser context. The exploitation does not require any special permissions but relies on user interaction, such as the user clicking a malicious link.

When malicious actors exploit the Shopware XSS vulnerability, the consequences can be severe, impacting both users and the integrity of the website. Attackers can capture sensitive session cookies, allowing them to impersonate users and perform unauthorized actions. Websites can also be defaced, inserting misleading content or redirecting users to malware-laden sites. Additionally, this vulnerability could be used as a launching point for phishing attacks, where users are tricked into divulging additional sensitive information. The trustworthiness of the affected online store may be severely diminished due to such security breaches.
