漏洞描述
中文描述:

Apache Tomcat是美国阿帕奇（Apache）基金会的一款轻量级Web应用服务器。该程序实现了对Servlet和JavaServer Page（JSP）的支持。 Apache Tomcat 10.0.0-M1版本至10.0.0-M5版本、9.0.0.M1版本至9.0.35版本和8.5.0版本至8.5.55版本中存在安全漏洞。攻击者可通过发出大量请求利用该漏洞导致服务器无法响应。

英文描述:

A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.
