Executive brief
OpenRapid RapidCMS, a content management system, is vulnerable to a security flaw that allows attackers to run malicious scripts in a user's browser. By tricking an administrator into clicking a specially crafted link, an attacker could potentially hijack their session, perform unauthorized actions, or steal sensitive information. This occurs because the system fails to properly clean data provided in the website's update component.
Technical details
A reflected Cross-Site Scripting (XSS) vulnerability exists in OpenRapid RapidCMS 1.3.1 within the /system/update-run.php (also referenced as /admin/system/update-run.php) component. The root cause is the improper neutralization of user-supplied input in the 'version' GET parameter before it is reflected back to the user. A remote, unauthenticated attacker can exploit this by crafting a malicious URL and inducing a victim, typically an authenticated administrator, to visit it. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session, which can lead to session hijacking or unauthorized administrative actions. No patch information was provided in the advisory.
