Netty is an asynchronous event-driven network application framework for
rapid development of maintainable high performance protocol servers and
clients.
Path to dependency file: /tests/test-sessions/test-gcloud-sessions/pom.xml
Path to vulnerable library: /home/wss-scanner/.m2/repository/io/netty/netty-codec-http2/4.1.3.Final/netty-codec-http2-4.1.3.Final.jar,/home/wss-scanner/.m2/repository/io/netty/netty-codec-http2/4.1.3.Final/netty-codec-http2-4.1.3.Final.jar
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
