CVE-2023-49965Public exploitNetwork attack vector

Browser script execution via unfiltered setup fields

Published Apr 5, 2024 · Updated Mar 27, 2025

Cross-site scripting in the setup page of SpaceX Starlink Gen 2 Router before 2023.48.0 allows remote attackers to execute browser scripts. The /setup handler places insufficiently filtered ssid and password values into the captive portal, allowing injected markup and JavaScript to run in the router origin. A victim must load an attacker-controlled page that posts the payload to the router; the resulting script can issue unauthenticated gRPC-Web commands to alter router settings or stow Dishy.
