Infinite open connection causes OctoRPKI to hang forever
GHSA-8cvr-4rrf-f244 · CVE-2021-3909 · GO-2022-0250
Published · Modified
Description
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.
