LOW 1.9

DescriptionCVE.org

A weakness has been identified in code-projects Simple Content Management System 1.0. This affects an unknown part of the file /web/admin/welcome.php. Executing a manipulation of the argument News Title can lead to cross site scripting. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

Stored cross-site scripting (XSS) in code-projects Simple Content Management System 1.0 allows authenticated high-privilege attackers to inject malicious scripts via the News Title parameter in /web/admin/welcome.php, affecting all versions of the product. The vulnerability requires user interaction (UI:R) to execute but has publicly available exploit code and a low CVSS score (2.4) due to high privilege requirements and limited impact scope.

Technical ContextAI

This is a stored XSS vulnerability (CWE-79: Improper Neutralization of Input During Web Page Generation) in a PHP-based content management system. The /web/admin/welcome.php file fails to properly sanitize or encode user input from the News Title parameter before storing it in a backend system and rendering it in web pages. When an authenticated administrator submits a crafted News Title containing JavaScript or HTML markup, the payload is stored persistently and executed in the context of other users' browsers without proper output encoding. The vulnerability affects the Simple Content Management System product (CPE: cpe:2.3:a:code-projects:simple_content_management_system:*:*:*:*:*:*:*:*), indicating all versions may be impacted.

RemediationAI

Upgrade to a patched version of code-projects Simple Content Management System if available from the vendor at https://code-projects.org/. As an interim mitigation, restrict access to /web/admin/welcome.php to trusted administrators only and implement input validation to reject or encode special characters (< > " ' &) in the News Title field before storage. Additionally, enforce output encoding (HTML entity encoding) when the News Title is rendered in web pages to prevent script execution. Web application firewalls can be configured to detect and block stored XSS payloads in the News Title parameter. Consult the vendor advisory and the public exploit at https://github.com/Xmyronn/simple-cms-stored-xss-news-title for additional technical details on the attack vector.
