CVE-2023-45288

一、漏洞信息
 漏洞编号：[CVE-2023-45288](https://nvd.nist.gov/vuln/detail/CVE-2023-45288)
 漏洞归属组件：[etcd](https://gitee.com/src-openeuler/etcd)
 漏洞归属的版本：3.4.14,3.4.7
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request s headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.

二、漏洞分析结构反馈
 影响性分析说明：
  该CVE为针对HTTP/2协议的潜在安全漏洞，它涉及到滥用CONTINUATION帧来导致服务器处理过量的头部数据。这种攻击可以消耗服务器资源，特别是内存和CPU时间，因为它需要解析并处理所有的HEADERS和CONTINUATION帧以保持HPACK（HTTP/2头压缩算法）状态。当请求的头部大小超过了服务端设定的最大头部字节数（MaxHeaderBytes），虽然额外的头部信息不会被存储，但仍然会被解析。这意味着即使这些请求最终将被拒绝，服务器依然会花费资源去解析它们。这为攻击者提供了一种方式，可以通过发送大量的头部数据让HTTP/2端点进行不必要的工作。尤其是当这些头部数据使用了Huffman编码时，解码成本对于接收方来说可能非常高，而对攻击者来说则相对便宜。（对应patch fix:https://github.com/golang/go/commit/e55d7cf8435ba4e58d4a5694e63b391821d4ee9b）
