CVE-2024-36248Network attack vector

External-service impersonation via hardcoded API keys

Published Nov 26, 2024 · Updated Nov 4, 2025

Hard-coded credentials in Sharp and Toshiba Tec MFP firmware allow attackers to impersonate devices when accessing external services. The main binary embeds private Google API keys and OAuth client domain identifiers in sub_2146D54(); the listed domains were unregistered, allowing registrants to receive printer traffic. Exploitation requires obtaining the embedded credentials and controlling a listed domain; the bounded consequence is unauthorized receipt or modification of external-service data.
