Description

Unisite CMS version 5.0 contains a stored Cross-Site Scripting (XSS) vulnerability in the "Report" functionality. A malicious script submitted by an attacker is rendered in the admin panel when viewed by an administrator. This allows attackers to hijack the admin session and, by leveraging the template editor, upload and execute a PHP web shell on the server, leading to full remote code execution.
