Description

Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.14 and 6.7.0, a stored XSS vulnerability in SVG asset reuploads allows authenticated users with asset upload permissions to bypass SVG sanitization and inject malicious JavaScript that executes when the asset is viewed. This has been fixed in 5.73.14 and 6.7.0.

Attack-Flow Graph

Executive Summary

This vulnerability is a stored Cross-Site Scripting (XSS) issue in the Statamic content management system. It occurs when authenticated users who have permission to upload assets reupload SVG files. These SVG files bypass the sanitization process, allowing the injection of malicious JavaScript code. This malicious code then executes when the SVG asset is viewed.

Impact Analysis

The vulnerability can lead to the execution of malicious JavaScript in the context of users viewing the compromised SVG assets. This can result in unauthorized actions such as stealing user credentials, session hijacking, or performing actions on behalf of the user. Since the vulnerability allows code injection with high impact on confidentiality and integrity, it poses a significant security risk.

Mitigation Strategies

To mitigate this vulnerability, immediately upgrade Statamic to version 5.73.14 or 6.7.0 or later, where the stored XSS vulnerability in SVG asset reuploads has been fixed.

Additionally, restrict asset upload permissions to trusted users only, as the vulnerability requires authenticated users with asset upload permissions.
