Prolink 4G LTE Mobile Wi-Fi DL-7203E V4.0.0B05 is vulnerable to Cross Site Scripting (XSS) in the /reqproc/proc_get endpoint. The vulnerability arises because the cmd parameter does not properly sanitize input and the response is served with a Content-Type of text/html. This behavior allows the browser to execute injected JavaScript code.
CWE-79
