CVE-2021-21409 (Medium) detected in netty-all-4.0.56.Final.jar #129
Netty is an asynchronous event-driven network application framework for
rapid development of maintainable high performance protocol servers and
clients.
Path to vulnerable library: /sdk/spring/azure-spring-data-gremlin/package/apache-tinkerpop-gremlin-server-minimal-3.3.4.tar/apache-tinkerpop-gremlin-server-minimal-3.3.4/lib/netty-all-4.0.56.Final.jar
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. This was fixed as part of 4.1.61.Final.
