RiteCMS Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in RiteCMS version 3.1.0. This vulnerability allows attackers to execute arbitrary code in the context of a user's browser by sending a crafted payload. The issue arises in the administrative node viewing endpoint, where URL or path parameters are not properly encoded before being rendered on the page. As a result, an attacker can exploit this vulnerability by manipulating the request to include malicious scripts, which are then executed in the browser of anyone who visits the affected URL. This vulnerability does not require authentication, increasing its potential impact.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can execute scripts in the context of the victim's browser session.

Reproduction

To reproduce this vulnerability, send an HTTP GET request to the administrative node viewing endpoint, such as '/admin.php' or '/node/view/*'. Include a crafted payload in the query or path that exploits the lack of proper output encoding. When the request is processed, the injected script will be executed in the browser of the user who accesses the URL.
