Cyclos 4.14.7 – ‘groupId’ DOM Based Cross-Site Scripting (XSS)

A Dom-based Cross-site scripting (XSS) vulnerability at registration account in Cyclos 4 PRO.14.7 and prior allows remote attackers to inject arbitrary web script or HTML via the 'groupId' parameter. An attacker sends a draft URL [IP]/#users.users.public-registration!groupId=1%27%22%3E%3Cimg%20src=x%20onerror=alert(document.domain)%3E to victim. When a victim opens the URL, XSS will be triggered.

Mitigation:

Input validation and output encoding should be used to prevent XSS attacks.
