OpenRapid RapidCMS Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in OpenRapid RapidCMS version 1.3.1. The issue resides in the '/system/update-run.php' endpoint, where the 'version' GET parameter is not properly sanitized, allowing remote, unauthenticated attackers to inject malicious scripts. This vulnerability requires user interaction, as the crafted URL must be accessed by an authenticated administrator.

Impact

Exploitation of this vulnerability allows for cross-site scripting, where injected scripts are executed in the context of the user's session.

Reproduction

To reproduce this vulnerability, a remote, unauthenticated attacker can create a URL that includes a malicious script in the 'version' GET parameter. When an authenticated administrator clicks on this URL, the script executes, taking advantage of the administrator's session.
