Title: Fifthplay S.A.M.I - Service And Management Interface Unauthenticated Stored XSS
Advisory ID: ZSL-2020-5561
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (4/5)
Release Date: 28.01.2020

Summary

Description

The application suffers from an unauthenticated stored XSS through POST request. The issue is triggered when input passed via several parameters is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. The application interface also allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions if a user visits a malicious web site.
