CVE-2022-45477Network attack vector

Unauthenticated code execution via server instructions

Published Dec 5, 2022 · Updated Apr 24, 2025

Missing authentication in the Telepad server through 1.0.7 allows remote attackers to execute arbitrary code via crafted instructions. The desktop server's network instruction handler accepts and executes remote-control instructions without authenticating or authorizing the sender. Any network-reachable server is exposed to commands running with the server process's desktop privileges; lower-level protocol details are undisclosed.
