What it is

A Server-Side Request Forgery vulnerability exists in sat_proxy.php in Zenith Satellite Tracker 1.0. The script accepts an attacker-controlled address URL parameter and passes it to curl_setopt(CURLOPT_URL) without host or scheme validation. An unauthenticated remote attacker can leverage this to make arbitrary HTTP and HTTPS requests from the server to internal networks or cloud metadata services, potentially obtaining sensitive information or pivoting to further attacks.
