A reflected cross-site scripting (XSS) vulnerability exists in Rukovoditel CRM version 3.6.4 and earlier in the Zadarma telephony API endpoint (/api/tel/zadarma.php). The application directly reflects user-supplied input from the 'zd_echo' GET parameter into the HTTP response without proper sanitization, output encoding, or content-type restrictions.
