Description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 2.2.3, a stored cross-site scripting (XSS) vulnerability exists in the Filerise application due to improper handling of uploaded SVG files. The application accepts user-supplied SVG uploads without sanitizing or restricting embedded script content. When a malicious SVG containing inline JavaScript or event-based payloads is uploaded, it is later rendered directly in the browser whenever viewed within the application. Because SVGs are XML-based and allow scripting, they execute in the origin context of the application, enabling full stored XSS. This vulnerability is fixed in 2.2.3.

Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in the FileRise web-based file manager prior to version 2.2.3. It occurs because the application improperly handles uploaded SVG files by accepting user-supplied SVGs without sanitizing or restricting embedded scripts. Malicious SVG files containing inline JavaScript or event-based payloads can be uploaded and later rendered in the browser within the application, executing scripts in the application's origin context and enabling full stored XSS attacks.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary JavaScript in the context of the FileRise application when users view the malicious SVG files. This can lead to theft of user credentials, session hijacking, unauthorized actions performed on behalf of users, and potential compromise of sensitive data accessible through the application.

Mitigation Strategies

Upgrade the FileRise application to version 2.2.3 or later, as this version contains the fix for the stored cross-site scripting (XSS) vulnerability related to SVG file uploads. Additionally, avoid accepting or rendering SVG files from untrusted sources until the upgrade is applied.
