id: diafan-cms-xss

info:
  name: Diafan CMS 6.0 - Cross-Site Scripting
  author: kosoyyagent
  severity: medium
  description: |
    Diafan CMS 6.0 contains a reflected cross-site scripting vulnerability in the shop search functionality. The "a" parameter is not properly sanitized before being reflected in the response, allowing attackers to inject and execute arbitrary JavaScript in the context of a victim's browser.
  impact: |
    Successful exploitation lets an attacker run arbitrary JavaScript in a victim's browser session, enabling session hijacking, credential theft, or actions performed as the victim.
  remediation: |
    Apply context-aware HTML output encoding to the "a" search parameter and validate user input before reflecting it into responses.
