CVE-2024-47865Public exploitNetwork attack vector

Unauthenticated firmware downgrade via exposed upgrade endpoint

Published Nov 20, 2024 · Updated Nov 20, 2024

Missing authentication in Rakuten Turbo 5G firmware 1.3.18 and earlier allows remote attackers to install or downgrade device firmware. The /upgrade.cgi endpoint accepts an uploaded firmware image in a POST request without verifying authentication before flashing it. Network access to the device management address is sufficient, and a successful request changes the installed image and reboots the device.
