Microweber CMS 2.0 - Reflected XSS in Admin Page Creation

id: CVE-2025-51502

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.
