漏洞描述
中文描述:

EasyApache是美国阿帕奇（Apache）基金会的一个功能强大且易于使用的工具，内置在WHM/cPanel中，可以使用它来更新和配置Apache web服务器。 Apache EasyApache 存在代码问题漏洞，该漏洞源于将NULL指针指向MOD_HTTP2、MOD_SESSION和MOD_PROXY_HTTP。

英文描述:

Apache HTTP Server protocol handler for the HTTP/2 protocol checks received request headers against the size limitations as configured for the server and used for the HTTP/1 protocol as well. On violation of these restrictions and HTTP response is sent to the client with a status code indicating why the request was rejected. This rejection response was not fully initialised in the HTTP/2 protocol handler if the offending header was the very first one received or appeared in a a footer. This led to a NULL pointer dereference on initialised memory, crashing reliably the child process. Since such a triggering HTTP/2 request is easy to craft and submit, this can be exploited to DoS the server. This issue affected mod_http2 1.15.17 and Apache HTTP Server version 2.4.47 only. Apache HTTP Server 2.4.47 was never released.
