| Título | feelec-yishu feelcrm-os 1.0.0 Cross Site Scripting |
|---|
| Descrição | FeelCRM 1.0.0 is affected by an authenticated reflected cross-site scripting vulnerability in the `/Crm` endpoint. The attacker-controlled `redirect_url` GET parameter is passed to `Crm\Controller\IndexController::index()`, processed by the ThinkPHP `U()` helper, and then rendered without HTML attribute encoding in the iframe `src` attribute at `App/Feelcrm/Crm/View/Index/index.html`. An attacker can craft a URL such as `http://TARGET/Crm?redirect_url=%22%20onload=alert(/xss/)%20%22`; when an authenticated CRM user opens the link, the quote closes the iframe attribute and injects an `onload` event handler. The supplied reproduction demonstrates successful JavaScript execution through an alert displaying `/xss/`. The vulnerability requires the victim to have a valid CRM session and visit the crafted URL, and may allow execution of same-origin JavaScript, access to data available to the victim, and authenticated CRM actions within the victim's permissions. |
