CVE-2024-31079: NGINX HTTP/3 QUIC vulnerability
First published: Wed May 29 2024(Updated: )
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed HTTP/3 requests can cause NGINX worker processes to terminate or cause other potential impact. This attack requires that a request be specifically timed during the connection draining process, which the attacker has no visibility and limited influence over.
