Vulnerability from github – Published: 2021-11-10 20:15 – Updated: 2023-10-02 15:56

Summary

Infinite open connection causes OctoRPKI to hang forever

Details

OctoRPKI (github.com/cloudflare/cfrpki/cmd/octorpki) does not limit the length of a connection, allowing for a slowloris DOS attack to take place which makes OctoRPKI wait forever. Specifically, the repository that OctoRPKI sends HTTP requests to will keep the connection open for a day before a response is returned, but does keep drip feeding new bytes to keep the connection alive.
