Description Preview
A cross-site scripting (XSS) vulnerability exists in Quokka CMS version 0.4.0. The vulnerability is present in the 'quokka/admin/actions.py' component where the 'Username' parameter is not properly sanitized. This allows remote attackers to inject and execute arbitrary JavaScript code in the context of other users' browsers, potentially leading to session hijacking, credential theft, or other malicious actions.
Overview
Quokka is a content management system (CMS) built with Python and Flask. The vulnerability identified as CVE-2020-18702 is a reflected XSS vulnerability in version 0.4.0 of the software. The issue occurs because user input from the 'Username' parameter is not properly validated or sanitized before being rendered in the application's admin interface. An attacker can craft a malicious username containing JavaScript code that will be executed when viewed by other users, particularly administrators. This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting.
Remediation
To remediate this vulnerability, the following steps are recommended:
- Update to a newer version of Quokka if available that addresses this vulnerability.
- If updating is not immediately possible, implement proper input validation and output encoding for the 'Username' parameter in the 'quokka/admin/actions.py' component.
- Consider implementing Content Security Policy (CSP) headers to mitigate the impact of XSS vulnerabilities.
- Apply the patch referenced in the GitHub issue if available.
- Review other input fields in the application for similar vulnerabilities and ensure all user inputs are properly sanitized.
