安全公告/【CVE-2020-13943】

基本信息

漏洞名称:
受影响操作系统:Asianux
危险等级:中危
影响源码包:tomcat9
CVSS评分:4.3
发现日期:2023-08-05

漏洞描述

If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources.

修复方式

sudo apt update && sudo apt dist-upgrade
