Description Preview
osCommerce 2.3.4.1 contains a Cross-Site Scripting (XSS) vulnerability that allows authenticated users to inject malicious JavaScript code through the title section of newsletters. When this injected code is viewed by other users, particularly administrators, it executes in their browsers, potentially leading to session hijacking, credential theft, or other client-side attacks.
Overview
This vulnerability (CVE-2020-29070) affects osCommerce version 2.3.4.1. The issue occurs because the application does not properly sanitize or validate user input in the newsletter title field. Authenticated users can exploit this vulnerability by inserting malicious JavaScript code into newsletter titles. When these newsletters are viewed by other users, the injected code executes within their browser context, potentially allowing attackers to steal cookies, session tokens, or perform actions on behalf of the victim. This is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting.
Remediation
To address this vulnerability, system administrators should:
- Update to the latest version of osCommerce or CE-Phoenix (the community edition fork of osCommerce) that contains the security patch.
- If immediate updating is not possible, implement input validation and output encoding for the newsletter title field.
- Consider implementing Content Security Policy (CSP) headers to mitigate the impact of XSS vulnerabilities.
- Review user permissions to limit who can create and edit newsletters.
- Monitor the official osCommerce forums and GitHub repository for security updates and patches.
