Advisory ID: ZSL-2019-5543
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 30.11.2019

Description

The application suffers from multiple CSRF and XSS vulnerabilities. The application 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 with administrative privileges if a logged-in user visits a malicious web site. Input passed to several GET/POST parameters is not properly sanitised 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.
