While some DoS flaws are classified as Moderate, \u201cMadeYouReset\u201d is Important because of the limited barriers (no specialized tooling or advanced scripting) to exploitation which directly impacts service availability. The vulnerability arises from an implementation weakness in HTTP/2 stream reset handling \u2014 malformed client requests can trigger server-side resets without incrementing abuse counters, allowing an attacker to bypass built-in request throttling and overhead limits. Since these resets consume CPU and memory resources and can be generated at scale over a single TCP/TLS connection, a remote attacker could exhaust server capacity quickly, impacting all legitimate clients.",

CWE

CWE-400 - Uncontrolled Resource Consumption

Summary

In Eclipse Jetty, versions <=9.4.57, <=10.0.25, <=11.0.25, <=12.0.21, <=12.1.0.alpha2, an HTTP/2 client may trigger the server to send RST_STREAM frames, for example by sending frames that are malformed or that should not be sent in a particular stream state, therefore forcing the server to consume resources such as CPU and memory. For example, a client can open a stream and then send WINDOW_UPDATE frames with window size increment of 0, which is illegal. Per specification https://www.rfc-editor.org/rfc/rfc9113.html#name-window_update , the server should send a RST_STREAM frame. The client can now open another stream and send another bad WINDOW_UPDATE, therefore causing the server to consume more resources than necessary, as this case does not exceed the max number of concurrent streams, yet the client is able to create an enormous amount of streams in a short period of time. The attack can be performed with other conditions (for example, a DATA frame for a closed stream) that cause the server to send a RST_STREAM frame.
