CVE-2024-47609Public exploitNetwork attack vector

Server exit via mishandled TLS accept error

Published Oct 1, 2024 · Updated Nov 21, 2024

Improper exception handling in Hyperium Tonic 0.12.2 allows remote attackers to stop a server through a malformed TLS connection. In tonic/src/transport/server/incoming.rs, handle_accept_error treats TLS InvalidData errors as fatal and breaks the accept loop instead of continuing. The service must use tonic::transport::Server with TCP/TLS, and successful exploitation terminates the server process without disclosing or modifying data.
