info:
name: Microweber CMS 2.0 - Reflected XSS in Admin Page Creation
author: nukunga
severity: medium
description: |
Reflected Cross-Site Scripting (XSS) exists in Microweber CMS 2.0 through the layout parameter on the /admin/page/create page. It allows arbitrary JavaScript to execute in the context of authenticated admin users.
impact: |
Authenticated attackers can execute arbitrary JavaScript in victim browsers through the layout parameter in page creation, potentially enabling session hijacking and credential theft.
remediation: |
Upgrade Microweber CMS to a version later than 2.0 that properly sanitizes the layout parameter.
