CVE-2023-43622 (CNNVD-202310-1641)
中文标题:
Apache HTTP Server 资源管理错误漏洞
英文标题:
Apache HTTP Server: DoS in HTTP/2 with initial windows size 0
漏洞描述
中文描述:
Apache HTTP Server是美国阿帕奇（Apache）基金会的一款开源网页服务器。该服务器具有快速、可靠且可通过简单的API进行扩充的特点。 Apache HTTP Server 2.4.55版本至2.4.57版本存在资源管理错误漏洞，该漏洞源于攻击者打开初始窗口大小为0的HTTP/2连接，能够无限期地阻止Apache HTTP Server中对该连接的处理，这可以耗尽服务器中的工作资源。
英文描述:
An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the server, similar to the well known "slow loris" attack pattern. This has been fixed in version 2.4.58, so that such connection are terminated properly after the configured connection timeout. This issue affects Apache HTTP Server: from 2.4.55 through 2.4.57. Users are recommended to upgrade to version 2.4.58, which fixes the issue.
