Executive Summary

This is a reflected Cross-Site Scripting (XSS) vulnerability in the feelcrm-os CRM system affecting the redirect_url parameter in the /Crm endpoint. The application inserts user-controlled input into an iframe's src attribute without proper encoding, allowing attackers to inject malicious JavaScript code.

Detection Guidance

To detect this reflected XSS vulnerability in feelcrm-os, monitor HTTP requests to the /Crm endpoint for the redirect_url parameter containing suspicious payloads like quotes or onload handlers. Use tools like Burp Suite or OWASP ZAP to intercept and inspect requests. Check application logs for repeated attempts with encoded or unusual redirect_url values.

Impact Analysis

An attacker could exploit this to execute arbitrary JavaScript in your authenticated CRM session. This may lead to unauthorized access to sensitive CRM data, execution of same-origin requests, or performing actions on your behalf without your knowledge.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, potentially violating GDPR's data protection requirements and HIPAA's security rules for protected health information. Organizations using this CRM may face compliance violations if exploited.

Mitigation Strategies

Immediately apply input validation to reject malicious characters in the redirect_url parameter. Implement HTML-attribute encoding for the parameter before rendering it in the iframe src attribute. Add a restrictive Content Security Policy (CSP) to limit script execution. Temporarily disable the /Crm endpoint if a patch is unavailable.
